  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.

  Several aliphatic 2-alkanols with varying chain length has been efficiently resolved by their acetylation using vinyl acetate/PPL in diisopropyl ether. The effect of solvent polarity, position and type of unsaturation and chain length has been probed. This has led to more convenient synthesis of some insect pheromones.
