Synthesis of Acrylonitriles via Mild Base Promoted Tandem Nucleophilic Substitution-Isomerization of α-Cyanohydrin Methanesulfonates

摘要

We have developed an efficient synthesis of acrylonitriles via mild base promoted tandem nucleophilic substitution-isomerization of α-cyanohydrin methanesulfonates with alkenylboronic acids.This transition metal-free protocol works under simple and mild condi-tions and offers good chemical yields for a wide range of substrates and demonstrates good functional group tolerance.
