An improved synthesis of β-cyano- l -alanine esters and amides

Wang, Guoxin,Chen, Longjian,Cai, Xiaodan,Li, Zigang,Luo, Ming

, p. 309 - 312 (2016/01/20)

We have developed a novel, mild, efficient, and scalable protocol for the synthesis of N-protected β-cyano-l-alanine esters or -amides from N-protected l-asparagin. This protocol avoided the use of toxic or unpleasant reagents and was easy to operate in laboratory.
