Abstract

Water and ethyl diazoacetate were found to be matched components for generating highly reactive nucleophilic oxonium ylide in the presence of a dirhodium acetate catalyst. Simultaneous trapping of the oxonium ylide intermediate with aryl imines gave beta-aryl isoserine derivatives with high diastereoselectivity.

摘要

水和乙基重氮乙酸酯在醋酸二铑催化剂的存在下被发现是生成高反应性亲核氧翁叶立德的匹配组分。同时用芳基亚胺捕获氧翁叶立德中间体得到了具有高非对映选择性的β-芳基异丝氨酸衍生物。
