A metal-free method for performing the Strecker reaction of N-tosylaldimines with ethyl cyanoformate in dimethylsulfoxide (DMSO) has been developed. Various types of N-tosyl-aldimines undergo the cyanation to provide the N-protected α-amino nitriles. This uncatalyzed protocol requires neither elevated temperature nor high pressure for the cyanations.

二甲基亚砜(
DMSO)中将N-托烯基醛
肟与乙基
氰基
甲酸酯进行斯特雷克反应。各种类型的N-托烯基醛
肟都能进行
氰化反应,生成N保护的α-
氨基腈。这一无催化剂的协议不需要升高温度或高压进行
氰化反应。
