A collective asymmetric synthesis of phenanthroindolizidine and phenanthroquinolizidine alkaloids (-)-antofine, (-)-cryptopleurine, (-)-tylophorine, and (-)-tylocrebrine was achieved by means of a reaction sequence involving efficient generation of chiral homoallylic amine intermediates by asymmetric allylation of the corresponding tert-butanesulfinyl imine. From these intermediates, the pyrrolidine and piperidine rings were constructed by means of an intramolecular SN2 substitution reaction and a ring-closing metathesis reaction, respectively. The unusual C5-methoxy-substituted phenanthrene moiety of (-)-tylocrebrine was generated by means of an InCl3-catalyzed cycloisomerization reaction of an o-propargylbiaryl compound.

(Chemical Equation Presented) A convergent strategy involving a base-mediated silyl transfer/acylation for fragment coupling and a tandem process consisting of nitro reduction and acyl transfer can be employed to construct strained, bicyclic macrolactams (see scheme). The tetracyclic core of the tetrapetalones, which are effective lipoxygenase inhibitors, can be prepared by using an IIII-promoted cyclization.

Reaction of the second-generation Grubbs metathesis catalyst [RuCl 2(=CHPh)(H2IMes)(PCy3)] (2) (H2IMes = 1,3-dimethyl-4,5-dihydroimidazol-2-ylidene) with primary alcohols in the presence of a base produced the complexes [RuClH(CO)(PCy3) 2] (3) and [RuClH(CO)(H2IMes)(PCy3)] (5). When benzyl alcohol was used, the ruthenium phenyl complexes [RuClPh(CO)(PCy 3)2] (4) and [RuClPh(CO)(H2IMes)(PCy 3)] (7) were formed in addition to 3 and 5. Complex 7, characterised by an X-ray structure analysis, was also formed on exposure of 2 to oxygen. The isomerization and hydrogenation activity of 7 was determined and compared with that of 3 and 4. ( Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003).

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.246047-72-3, Name is (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium, molecular formula is C46H65Cl2N2PRu.

Second generation Grubbs catalyst [RuCl2(H2IMes)(PCy3)(CHPh)] initiates regio- and stereoselective cross-metathesis of silylacetylenes with 1-alkenes and alpha,omega-dienes leading to the formation of E-2-silyl-1,3-dienes and E-2-silyl-1,3,n-trienes, respectively. Efficient progress of the reaction is achieved by using 5-8 mol% of the benzylidene initiator and twofold excess of olefin (with respect to silylacetylene) as well as ethereal solution of HCl (10-20 mol% with respect to the catalyst) as an activator. The reaction is proposed to be catalysed by alkylidene complex [RuCl2(H2IMes)(PCy3)(CHR)] (where R = alkyl, n-alkenyl) generated from the benzylidene initiator, and proceed via initial interaction of a metal alkylidene with a triple bond.

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.Safety of (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium, you can also check out more blogs about246047-72-3

We report a new gold-catalyzed deoxygenated cyclization of cis-2,4-dien-1-als with external nucleophiles at ambient temperatures, which leads to a 1,4-double nucleophilic addition to the newly formed cyclopentene ring. The use of this cyclization is reflected not only by its compatibility with a wide scope of nucleophiles, but also by a facile construction of complex frameworks in diversified approaches. Copyright

Starting from the conveniently available ex-chiral pool building block (R,R)-hexa-1,5-diene-3,4-diol, the ten-membered ring lactones stagonolide E and curvulide A were synthesized using a bidirectional olefin-metathesis functionalization of the terminal double bonds. Key steps are (i) a site-selective cross metathesis, (ii) a highly diastereoselective extended tethered RCM to furnish a (Z,E)-configured dienyl carboxylic acid and (iii) a Rulipase-catalyzed dynamic kinetic resolution to establish the desired configuration at C9. Ring closure was accomplished by macrolactonization. Curvulide A was synthesized from stagonolide E through Sharpless epoxidation.

Cyclophane-containing bis(2-amino-1,8-naphthyridine) moieties attached to variable linkers at the C2-position (linker B) were synthesized as cyclic mismatch-binding ligands (CMBLs). Ring-closing metathesis (RCM) is used as a key step for the introduction of double bonds at the linker B. Decreasing the size of the linker of the substrate, formation of the RCM products with an increasing trans/cis (E/Z) ratio was observed with moderate to high overall yields. Concentration-dependent fluorescence spectra were observed for CMBLs with longer linkers (n=3), whereas concentration-independent spectra were observed for CMBLs with shorter linkers (n=2 and/or 1) with a marked exception of the E-alkene 6 a. Concomitant changes in the absorption as well as in the fluorescence spectra were also observed for the CMBLs with an increasing hydrophobicity of the solvent. Absorption and fluorescence spectra of the CMBLs in solutions containing 99?100 % methanol resembled to that of the monomer. The binding behavior of these CMBLs with repeat DNA structures was investigated by using a surface plasmon resonance (SPR) assay and circular dichroism (CD) spectra. The cyclic E-alkenes 1 a (n=3) and 3 a (n=2) show an orthogonal binding relationship with d(CCTG)9 and d(CAG)9. However, the selectivity for the cyclic Z-alkenes increased with decreasing the length of the linker from compound 2 b (n=3) to compound 7 b (n=1). These compounds display a large molecular diversity, which allowed the tuning of the binding affinity and selectivity of the CMBLs by varying the linkers towards various biologically significant repeat DNA structures.

Novel regioselective ring closing ene-yne metathesis provided an efficient access to different substituted 1-benzazepine scaffolds. The reported synthetic approach could also be used as a powerful tool for the selective formation of a highly functionalizable 2-benzazepine core. This synthetic protocol was even proved to be an efficient way to obtain a functionalizable benzazocine derivative. By modifying the structure of the starting materials, the optimized cyclization finally proved to be a suitable technique to obtain five- and six-membered lactams, enhancing the synthetic application of our method. Five- and six-membered lactams were efficiently prepared by ring-closing metathesis involving the loss of ethylene moiety and affording highly functionalizable compounds showing both electron-withdrawing substituents and electron-donor groups.

An expeditious click-click cyclize strategy for the assembly of medium-sized heterocyclic rings is described. The sequence involves the reaction of cycloprop-2-ene carboxylic acids with unsaturated amines to furnish amides, which are further subjected to a Cu-catalyzed directed carbomagnesiation and a ring-closing olefin metathesis reaction. This methodology allows for the efficient preparation of lactams with ring sizes up to 10.

The highest initiation rate of any reported ruthenium-based catalyst was found for the new olefin-metathesis catalyst [(H2IMes)(3-Br-py)2(Cl)2Ru=CHPh] (1), which was synthesized in one step from commercially available reagents. Complex 1 is highly efficient for the cross metathesis of acrylonitrile, which is generally a poor substrate for metathesis reactions (e.g., see scheme). Mes = 2,4,6-trimethylphenyl.
