  Enantioselective esterifications of unsaturated alcohols mediated by a lipase prepared from Pseudomonas sp

  摘要：

  Competition experiments and measurements of enantioselectivities were used to develop a simple active-site model (Figure 1) for resolutions of beta-hydroxy-alpha-methylene carbonyl compounds III via acyl transfers mediated by lipase from Pseudomonas sp. (AK). Further experiments were used to test and refine this model with respect to resolutions of allylic, propargylic, homopropargylic, and other alcohols (Tables I-IV, respectively). The model proved extremely reliable for predicting the sense of the asymmetric induction, and the combined data collected in this paper give an indication of what structural features of the substrates can be correlated with high enantioselectivities in these resolutions. Furthermore, the results account for the conspicuous reversal of enantioselectivity previously observed in resolutions of gamma-hydroxy-alpha,beta-unsaturated esters 35. Kinetic resolutions of two substrates (allenol 14 and dienol 9) via asymmetric epoxidations were performed for comparison with the methodology presented in this paper.

  Naturally occurring L-783277 which belongs to 14-membered resorcylic acid lactones (RALs) turned out to be a potent kinase inhibitor against MEK (MAP kinase kinase). We successfully accomplished efficient and enantioselective total synthesis of L-783277 based on convergent assembly of one aromatic unit and two chiral building blocks with efficient orthogonal protection-deprotection strategy. Three

  Asymmetric epoxidation of conjugated dienes and enynes catalyzed by (salen)Mn(III) complex 1 takes place with high chemoselectivity to afford monoepoxides exclusively. Reactions of cis-enynes proceed with very high levels of asymmetric induction, with trans-alkynyl epoxides as the major products.
