An organocatalytic asymmetric cascade reaction has been developed for the synthesis of highly substituted pyrrolidines having a stereogenic quaternary centre at the 3-position. N-Tosyl aminomethyl enone and trans-α-cyano-α,β-unsaturated ketone were utilized as the reaction partners in this method. Cinchonidine derived bifunctional amino-squaramide catalysts were the best to obtain the products in high
已经开发了有机催化不对称级联反应,用于合成在3-位具有立体异构的季中心的高度取代的吡咯烷。该方法以N-甲苯磺酰基氨基甲基烯酮和反式-α-氰基-α,β-不饱和酮为反应伙伴。辛可尼定衍生的双官能氨基-方酸酰胺催化剂是获得高对映体和非对映体选择性的最佳产品。
