Methyl cyanoformate (1), well known as an electrophile in regioselective synthesis of β-keto esters from lithium enolates, reacted as a nucleophile with cyclic α-phenylthiomethyl α,β-unsaturated carbonyl compounds (II) to give α-cyanomethyl αβ-unsaturated carbonyl compounds (III) in high yields. Compound 1 also reacted with α,β-unsaturated carbonyl compounds (I) to give β-cyano ketones (IV).
