Using cyanoacetic acid as a masked electrophile, a new cyanomethylation reaction of amines and carboxylic acids was developed, producing a variety of α‐aminonitriles and cyanomethyl esters with good yields and excellent functionality tolerance. This protocol features simple manipulation, inexpensive reagents, and a wide substrate scope. Iodoacetonitrile was generated in situ from the iodination–decarboxylation
使用氰基乙酸作为掩蔽的亲电试剂,开发了一种新的胺和羧酸的氰基甲基化反应,以高收率和出色的功能耐受性生产了多种α-氨基腈和氰基甲基酯。该方案具有操作简单,试剂便宜和底物范围广的特点。在此转化过程中,氰基乙酸的碘化-脱羧反应原位生成了碘乙腈。
