A protecting group free synthesis of 2,3-cis substituted hydroxypyrrolidines is reported. Two novel reaction methodologies allow for the stereoselective formation of cyclic carbamates from olefinic amines, and the formation of primary amines via a Vasella/reductive amination reaction, both performed in aqueous media.
报道了一种无保护基团合成2,3-顺式取代羟基吡咯烷的方法。两种新颖的反应方法能够在水性介质中,从烯胺立体选择性地形成环状氨基甲酸酯,并通过瓦塞拉/还原胺化反应形成伯胺。
