  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.

  demonstrated a very general method for the preparation of essentially any terminal 2,3-allenol from the corresponding alkynols, which may be easily available from propargylic alcohols by alkylation, or from terminal alkynes by deprotonation and 1,2-addition with aldehydes or ketones, and subsequent base-catalyzed triple-bond migration. We have demonstrated a very general method for the preparation of essentially

  yields up to 99%. In the case of α,β-unsaturated alkenyl ketones, α-substituted cycloalkenones were reduced with up to 99% ee, while more substituted and acyclic derivatives exhibited lower induction. For α,β-ynones, it was found that highly branched aliphatic ynones were reduced with optimal induction up to 90% ee, while reduction of aromatic and linear aliphatic derivatives resulted in more modest enantioselectivity

  据报道，制备对映体纯度高的手性烯丙基和炔丙基醇的方法轻而易举。在最佳条件下，TarB-NO 2和NaBH 4在25°C下于1 h内将炔基和烯基酮还原，生成对映体过量的手性炔丙基和烯丙基醇，收率高达99％。在α，β-不饱和烯基酮的情况下，α-取代的环烯酮的还原度最高可达99％ee，而更多被取代和无环的衍生物则显示出较低的诱导率。对于α，β-炔酮，发现高支化的脂族炔酮在最高达90％ee的情况下以最佳诱导被还原，而芳族和线性脂族衍生物的还原导致更适度的对映选择性。使用（升源自（l）-酒石酸的）-TarB-NO 2试剂，我们通常获得具有（R）构型的高度对映体富集的手性烯丙基和炔丙基醇。由于先前的模型和饱和类似物预测的（S）构型的炔丙基产物的减少，因此进行了一系列新的机理研究，以确定过渡态芳族，烯基和炔基酮的可能取向。

  1,3-acyloxy migration of propargyl α-ketoesters and a carbonyl-ene cyclization of in situ generated allenyl esters. DFT calculations suggest that the copper salt might play dual roles as both chloride abstractor facilitating the generation of highly active gold catalyst and Lewis acid promoting the stepwise intramolecular carbonyl-ene reaction.

  A new Au(I)-catalyzed method for the preparation of trisubstituted indolizines from easily accessible 2-propargyloxy-pyridines is reported. The reaction tolerates a wide range of functionality, allowing for diversity to be introduced in four distinct regions of the product (R, R1, R2, and Ar). The proposed mechanism proceeds via enol addition to an allenamide intermediate and explains the observed
