Total synthesis and structural elucidation of azaspiracid-1. Final assignment and total synthesis of the correct structure of azaspiracid-1

The molecular structure of azaspiracid-1, a neurotoxin isolated from mussels, has been elucidated by total synthesis which also enriched its supplies. The degradatively derived fragments of this marine biotoxin, compounds 5 (EFGHI), 6 (FGHI), and 40 (ABCD), were matched with synthetic materials, thus confirming their structural identities. Based on this detective work, a new structure of azaspiracid-1 (i.e., 1) was proposed and constructed by total synthesis. The final strategy for the total synthesis of azaspiracid-1 featured a dithiane anion (C21-C27 fragment) reacting with a pentafluorophenol ester (C1-C20 fragment) followed by a Stille-type union of an advanced allylic acetate substrate (C1-C 27 fragment) with a vinyl stannane as the main coupling processes to assemble the carbon skeleton of the molecule. In addition to the total synthesis of azaspiracid-1 (1), the syntheses of its C1-C20 epimer (2) and of several truncated analogues for biological investigations are described.

Synthesis and complexation of macrocycles containing two pyrazolone sub-units

The synthesis and characterization of several Ru(II) complexes with acyclic and macrocyclic ligands containing tautomerizable OH and fixed OCH3 5-pyrazolone heterocycles are described. From dipyrazolylmethane bidentate ligands L, RuL(bpy)2(PF6)2 and Ru(L-H+)(bpy)2PF6 complexes have been obtained. From the macrocycle with two CH3 and two OCH3 pyrazole sub-units, a series of complexes Ru(Mac)XY(PF6)2 (X,Y = DMSO, CH3CN, Py, Pz, dmPz) has been prepared. They show a behavior close to that of the analogous tetrapyrazole complexes but with slightly different complexing ability. In the case of the corresponding di OH macrocycle, coordination with Ru(DMSO)4Cl2 leads to unstable complexes.

Preparation of ammonia borane in high yield and purity, methanolysis, and regeneration

Ammonia borane (AB) is emerging as a promising solid hydrogen carrier, particularly for power generation in portable devices that employ proton-exchange membrane fuel cells. A preparative-scale synthesis of AB from sodium borohydride and ammonium salts in high yields (?95%) and very high purity (?98%) has been described. The first systematic study of a transitional metal-catalyzed alcoholysis of AB, comparison of the methanolysis to the hydrolysis of AB, and regeneration of AB from ammonium tetramethoxyborate also has been described.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.category: ruthenium-catalysts, you can also check out more blogs about10049-08-8

A 3-pyridyl-5,15-diazaporphyrin nickel(II) complex as a bidentate metalloligand for transition metals

3-Pyridyl-5,15-diazaporphyrin nickel(II) serves as a bidentate metalloligand for platinum(II), ruthenium(II), and rhenium(I) metal centers. Single-crystal X-ray diffraction analysis of these metal complexes unambiguously reveals the presence of a dative bond between the outer metal center and the meso-nitrogen atom. The UV/Vis absorption spectra of the complexes show substantially red-shifted bands which are perturbed by outer-metal coordination. This is due to the contribution of metal-to-ligand charge transfer interactions.

Syntheses, characterization and structure determination of {[CpRu(X)]2(eta2,mu2-dppe)2} complexes (X=Cl, N3; Dppe=Ph2PCH2CH2PPh2): Chelating vs. bridging behavior of a classical bidentate ligand

Phosphine substitution reactions between (eta5-C5H5)Ru(PPh3)2Cl (1) and 1,2-bis(diphenylphosphino)ethane (Ph2P(CH2)2PPh2, dppe), in refluxing benzene or in toluene at 80C afforded a mixture of complexes where dppe behaves both as a bridging and as a chelating ligand. CpRu(eta2-dppe)Cl (2) and {[CpRu(Cl)]2(eta2,mu2-dppe)2} (3) were separated by fractional precipitation from the reaction mother-liquor, and were characterized by 1H, 13C, 31P NMR, elemental analysis and IR spectroscopy. The (2):(3) ratio in the composition of the reaction product was found to be independent of the reaction time. In solution and at room temperature, (3) exists in both boat and chair conformers of a 10-membered ring, while at lower temperatures, and in the solid-state, only the chair conformer is observed. Compounds (2) and (3) undergo halide-displacement upon reacting with NaN3 in the presence of ethanol to yield CpRu(eta2-dppe)(N3) (4) and {[CpRu(N3)]2(eta2,mu2-dppe) 2} (5), respectively. The crystal structures of (3) and (5) were determined. Elsevier Science Ltd.

On the other hand, the reaction of 1 with X2PN(CHMe2)-PYY? {X2 = YY? = O2C6H4(L2)} gives the complex, [CpRu(eta1-L2)2PPh3]Cl. Both types of complexes are formed with X2PN(CHMe2)PYY? {X = Ph, YY? = O2C6H4 (L3)}. The reaction of 1 with (R),(S)-(H12C20O2)PN(CHMe2)PPh2 (L7) yields both cationic and neutral complexes, [CpRu{eta2-(L7)}PPh3]Cl and [CpRu{eta1-(L7)}2PPh3]Cl and [CpRu{eta2-(L7)}-Cl]. The reactions of optically pure diphosphazane, Ph2PN(*CHMePh)PPhY (Y = Ph (L8); Y = N2C3HMe2-3,5 (L9)) with 1 give the neutral and cationic ruthenium complexes, [CpRu{eta2-(Ph2PN(R)PPhY)}Cl] and [CpRu{eta2-(ph2PN(R)-PPhY)}PPh3]Cl. “Chiral-at-metal” ruthenium complexes of diphosphazanes have been synthesized with high diastereo-selectivity.

The reactions of [CpRu{eta2-(L8)}Cl] with mono or diphosphanes in the presence of NH4PF6 yield the cationic complexes, [CpRu{eta2-(L8)}{eta1-(P)}]PF6 {P = P(OMe)3, PPh3, Ph2P(CH2)nPPh2 (n = 1 or 2)}.
