Abstract
The o-nitrobenzylidene acetoacetic esters 1 dimerize in the presence of BuLi or LDA to give the cyclohexenes 2 in poor yield. Two diastereomer of 2b were isolated, whose configuration is deduced by nmr-spectroscopic methods.
摘要
邻硝基亚苄基乙酰乙酸酯1在丁基锂或二异丙基氨基锂存在下二聚生成环己烯2，产率较低。分离出了2b的两种非对映异构体，其构型通过核磁共振光谱法推导得出。
