Dimethylsulfoxide-Promoted Strecker Reaction of N-Tosylaldimines with Cyanoformate
Publication History
Publication Date:

Abstract
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.
Key words
N-tosylaldimine - ethyl cyanoformate - α-amino nitriles - Strecker reaction

We tried to isolate the intermediate 11 (R in 7 is 4-MeC6H4; Scheme [²] ) after 1 h of reaction time before and after work-up procedure. Under these conditions, we observed the formation of 9b instead of intermediate 11. This may mean that a small amount of moisture in the reaction mixture is sufficient to convert 11 into 9.
