The synthesis of new chiral highly functionalized zwitterionic bicyclic lactams starting from acyclic β-enaminoesters derived from (R)-(−)-2-phenylglycinol is described. The key step involved an intramolecular non-classical Corey–Chaykovsky ring-closing reaction of the corresponding sulfonium salts derived from β-enaminoesters. This methodology permits the generation of two or three new stereogenic
描述了以 ( R )-(-)-2-苯基甘氨醇衍生的无环 β-烯胺酯为原料合成新型手性高度官能化两性离子双环内酰胺。关键步骤涉及衍生自 β-烯胺酯的相应锍盐的分子内非经典 Corey-Chaykovsky 闭环反应。该方法允许产生两个或三个具有高非对映选择性的新立体中心。通过顺式-4-羟基-2-甲基哌啶及其相应的哌啶酸衍生物的立体控制全合成证明了这些中间体的实用性。
