Reactions of furylruthenium complexes with oxygen and trimethylsilyl azide

The reaction of the (alpha-alkoxyfuryl)ruthenium complexes 4 with oxygen opens the five-membered furyl ring to give the addition product [Ru]O 2CCR=CHCO2CH3, (5, [Ru] = Cp(PPh 3)2Ru). Further reactions of 5 with CH3I and with organic acid gave CH3O2CCR=CHCO2CH 3, (6), and HO2CCR=CHCO2CH3, (7), respectively. The reaction of 4 with TMSN3 [TMS = (CH 3)3Si] gives the ruthenium azide [Ru]-N3 and alpha-alkoxyfuran, which is readily hydrolyzed to lactone in acidic medium. Treatment of the cyclopropenylruthenium complex 11b containing a methyl crotonate group with TMSN3 affords the five-membered-ring triazole and [Ru]-CN. In this reaction cleavage of the C=C double bond of the three-membered ring could be caused by consecutive additions of TMSN3 to olefinic carbon atoms of intermediates formed during the reaction.

Polar cofacially fixed sandwich complexes: Do they demonstrate second harmonic generation (SHG)?

For the purpose of possible second harmonic generation (SHG) a cationic and a neutral sandwich unit were cofacially arranged in a three-step synthesis starting from 1,8-diiodonaphthalene. First, 1-cyclopentadienyl-8-iodonaphthalene (2) was formed, then the neutral ferrocenyl substituent was fixed in the 8-position by a Negishi cross-coupling reaction. The deprotonation of the cyclopentadienyl substituent, and the subsequent coordination of the half-sandwich fragments ML = [Fe(eta5-C5Me 5)]+, [Rh(eta5-C5Me 5)]2+, [Ir(eta5-C5Me 5)]2+, [Ru(eta6-C6H 6)]2+ to the cyclopentadienyl anion revealed the desired dinuclear complexes 1-[(eta5-cyclopentadienediyl)- (eta5-pentamethylcyclopentadienyl)iron(II)]-8- ferrocenylnaphthalene (5), 1-[(eta5-cyclopentadienediyl) (eta5-pentamethylcyclopentadienyl)rhodium(III)]-8- ferrocenylnaphthalene hexafluorophosphate (6PF6), 1-[(eta5-cyclopentadienediyl)(eta5- pentamethylcyclopentadienyl)iridium(III)]-8-ferrocenylnaphthalene hexafluorophosphate (7PF6), and 1-[(eta6-benzene) (eta5-cyclopentadienediyl)ruthenium(II)]-8-ferrocenylnaphthalene hexafluorophosphate (8PF6). The neutral complex 5 was oxidized to the paramagnetic cation 1-[(eta5-cyclopentadienediyl)- (eta5-pentamethylcyclopentadienyl)iron(III)]-8- ferrocenylnaphthalene hexafluorophosphate (5PF6). Compounds 3, 5PF6, 6PF6, and 7PF6 were characterized by X-ray structure determination; the neutral compound 3 crystallizes in the space group P21/c, whereas all of the cationic dinuclear complexes crystallize in the chiral space group C2221. A cyclic voltammetry study points to a predominant “through-space” interaction between the cationic sandwich unit and the neutral ferrocene substituent. The compounds 5PF6, 6PF6, 7PF6, and 8PF6 were subjected to hyper-Rayleigh scattering (HRS) and Kurtz-powder measurements. In both studies no SHG intensity could be observed.

Synthesis of substituted cycloalkene-1,1-dicarboxylates via olefin metathesis in water

A range of substituted cycloalkene-1,1-dicarboxylates was synthesized through olefin metathesis starting from readily available acylic malonate precursors in an efficient fashion. As a metathesis catalyst, a Grubbs II-type catalyst was used in these experiments, which were run in water and gave the cyclic malonate products with high conversions of 94-100%. The catalytic amount was in the range of 0.5-5 mol% dependent on the structure of the starting material. The generality of this metathesis reaction in water was demonstrated as well as its suitability for the preparation of five and six-membered and alkyl as well as aryl-substituted prochiral cycloalkene-1,1-dicarboxylates.

Design, synthesis, and biological evaluation of platensimycin analogues with varying degrees of molecular complexity

The molecular design, chemical synthesis, and biological evaluation of two distinct series of platensimycin analogues with varying degrees of complexity are described. The first series of compounds probes the biological importance of the benzoic acid subunit of the molecule, while the second series explores the tetracyclic cage domain. The biological data obtained reveal that, while the substituted benzoic acid domain of platensimycin is a highly conserved structural motif within the active compounds with strict functional group requirements, the cage domain of the molecule can tolerate considerable structural modifications without losing biological action. These findings refine our present understanding of theplatensimycin pharmacophore and establish certain structure-activity re lationships from which the next generation of designed analogues of thisnew antibiotic may emerge.

Ruthenium complexes of triazole-based scorpionate ligands transfer hydrogen to substrates under base-free conditions

The first ruthenium complexes of bulky tris(triazolyl)borate (Ttz) ligands were synthesized, fully characterized, and studied as transfer hydrogenation catalysts. The structures of the complexes were (eta6-arene)RuCl(N, N), where in each case N,N is a kappa2-Ttz or bis(triazolyl)borate (Btz) ligand (arene = p-cymene (1, 3, 5, 6), benzene (2), C6Me 6 (4); N,N = TtzPh,Me* (1, 2), TtzMe,Me (3, 4), Ttz (5), Btz (6)). All but 5 were crystallographically characterized, and notably for 1 and 2 a rearranged ligand structure is observed (as indicated by an asterisk). These complexes were all effective catalysts for transfer hydrogenation of aryl ketones in isopropyl alcohol with base co-catalyst, with rates that were accelerated by moisture-free conditions. Complexes 1 and 2 are also effective catalysts for base-free transfer hydrogenation, and with 1 hydrogenation of several base-sensitive substrates was demonstrated. The ability of 1 to serve as a hydrogenation catalyst without base is attributed primarily to steric bulk, and a preliminary mechanism for formation of that active catalyst is proposed.

Liquid-phase oxidation of alcohols by oxygen and nitrous oxide catalysed by Ru-Co oxide

Chemoselective catalysts in bulk or supported on gamma-Al 2O3 binary oxides RuIV-CoIII (Ru/Co = 1:1-1:2), prepared by co-precipitation, were used for liquid-phase oxidation of saturated and unsaturated primary and secondary alcohols to aldehydes and ketones with O2 or N2O. The catalysts can be separated by filtration and reused. No leaching of Ru or Co in solution was observed. The oxidation is enhanced by the presence of hydration water in the Ru-Co catalyst, which indicates the participation of active RuIV hydroxo species in the reaction. From XRD and TGA, the Ru-Co oxide can be approximated as a hydrous binary oxide comprising the amorphous RuO2 and heterogenite-3R cobaltic acid CoO(OH). The alcohol oxidation appears to occur by a nonradical mechanism, which may be viewed as an oxidative dehydrogenation of alcohols to form an aldehyde or ketone. H2-TPR shows that CoIII practically does not affect the oxidising ability of RuO2. This suggests that the cobalt is likely to enhance catalyst reoxidation by O 2 rather than to play a significant role in the alcohol dehydrogenation. The alcohol oxidation by N2O exhibits a close similarity to the oxidation by O2 but is much less efficient. Much more active catalysts are required to make the oxidation with N2O synthetically useful.

Evolution of the total synthesis of (-)-Okilactomycin exploiting a tandem oxy-cope rearrangement/oxidation, a petasis-ferrier union/rearrangement, and ring-closing metathesis

An effective, asymmetric total synthesis of the antitumor antibiotic (-)-okilactomycin (1), as well as assignment of the absolute configuration,has been achieved exploiting a convergent strategy. Highlights of the s ynthesis include a diastereoselective oxy-Cope rearrangement/oxidation sequence to install the C(1) and C(13) stereogenic centers, a Petasis-Ferrier union/rearrangement to construct the highly functionalized tetrahydropyranone inscribed within the 13-membered macrocycle ring, employing for the first time a sterically demanding acetal, an intramolecular chemoselective acylation to access an embedded bicyclic lactone, and an efficient ring-closing metathesis (RCM) reaction to generate the macrocyclic ring.

A Novel Conjugate of Bis[((4-bromophenyl)amino)quinazoline], a EGFR-TK Ligand, with a Fluorescent Ru(II)-Bipyridine Complex Exhibits Specific Subcellular Localization in Mitochondria

The epidermal growth factor receptor (EGFR) is a key target in anticancer research, whose aberrant function in malignancies has been linked to severe irregularities in critical cellular processes, including cell cycle progression, proliferation, differentiation, and survival. EGFR mutant variants, either transmembrane or translocated to the mitochondria and/or the nucleus, often exhibit resistance to EGFR inhibitors. The ability to noninvasively image and quantify EGFR provides novel approaches in the detection, monitoring, and treatment of EGFR-related malignancies. The current study aimed to deliver a new theranostic agent that combines fluorescence imaging properties with EGFR inhibition. This was achieved via conjugation of an in-house-developed ((4-bromophenyl)amino)quinazoline inhibitor of mutant EGFR-TK, selected from a focused aminoquinazoline library, with a [Ru(bipyridine)3]2+ fluorophore. A triethyleneglycol-derived diamino linker featuring (+)-ionizable sites was employed to link the two functional moieties, affording two unprecedented Ru conjugates with 1:1 and 2:1 stoichiometry of aminoquinazoline to the Ru complex (mono-quinazoline-Ru-conjugate and bis-quinazoline-Ru-conjugate, respectively). The bis-quinazoline-Ru-conjugate, which retains an essential inhibitory activity, was found by fluorescence imaging to be effectively uptaken by Uppsala 87 malignant glioma (grade IV malignant glioma) cells. The fluorescence imaging study and a time-resolved fluorescence resonance energy transfer study indicated a specific subcellular distribution of the conjugate that coincides with that of a mitochondria-targeted dye, suggesting mitochondrial localization of the conjugate and potential association with mitochondria-translocated forms of EGFR. Mitochondrial localization was further documented by the specific concentration of the bis-quinazoline-Ru-conjugate in a mitochondrial isolation assay.

Base-assisted cyclometalation and phosphorus-carbon bond cleavage in (arene)ruthenium(ii) complexes containing functionalized iminophosphorane- phosphine ligands Ph2PCH2P{=NP(=X)(OR)2}PH 2 (X = O, S; R = Et, Ph)

The bond-assisted cyclometalation and phosphorus-carbon bond cleavage in (Arene)ruthenium(II) complexes are discussed. The complexes contain functionalized iminophosphorane-phosphine ligands Ph2PCH 2P{=NP(=X)(OR)2}Ph2 (X = O, S; R = Et, Ph). It is found that the functionalized iminophosphorane-phosphines act as versatile ligands upon coordination to a (eta6-arene)-ruthenium(II) fragment. The results show that the ligands are used as templates for the construction and stabilization of unusual organometallic ruthenium(II) complexes.
