3-disubstituted pyrrolidines is reported that involves diastereoselective allylation of (R)-phenylglycinol-derived imines and a sequential hydrozirconation-cyclization. A number of pyrrolidine derivatives bearing aryl, heteroaryl, alkyl and alkenyl groups have been prepared in this way. Such compounds are useful building blocks in the synthesis of molecules of biological interest, as illustrated by
据报道,直接获得对映体纯的 2,3-二取代吡咯烷涉及 (R)-苯基甘氨醇衍生的亚胺的非对映选择性烯丙基化和顺序氢化锆化-环化。许多带有芳基、杂芳基、烷基和烯基的吡咯烷衍生物已经以这种方式制备。如脯氨酸衍生物和天然存在的生物碱 (-)-isoretrone-canol 的合成所示,此类化合物是合成具有生物学意义的分子的有用构件。
