We report herein two stereocomplementary approaches to erythro/trans and threo/cis vicinal amino diol subunits containing 2-pyrrolidinones (9 and 10) starting from the known enamides 7, easily available from malimides. The first approach consists of an epoxidation-reductive dehydroxylation procedure, and the second one is based on hydroboration-oxidation reactions. Using the second method, a formal asymmetric synthesis of (-)-detoxinine was achieved.
我们在此报告了两种立体互补方法,用于从已知的烯酰胺7开始合成含有2-吡咯烷酮(9和10)的赤式/反式和顺式/顺式邻位氨基二醇亚基,烯酰胺7可从马来酰亚胺轻松获得。第一种方法包括环氧化-还原脱羟基过程,第二种方法基于硼氢化-氧化反应。使用第二种方法,实现了(-)-去毒素宁的形式不对称合成。
