studied the influence of different reaction conditions on the conjugated addition of β-keto sulfones to α,β-unsaturated aldehydes catalyzed by silyl prolinol ethers. Small changes in the starting material and/or in the experimental protocol are able to produce significant variations in the structures of the final products. The high chemical versatility of the resulting Michael adducts make possible their
我们研究了不同反应条件对甲硅烷基脯氨醇醚催化 β-酮砜与 α,β-不饱和醛共轭加成的影响。起始材料和/或实验方案的微小变化能够在最终产品的结构中产生显着变化。所得迈克尔加合物的高化学多功能性使其可用于各种串联和一锅反应,以提供带有多个手性中心的多取代环状产物。
