Ram,Verma

, p. 624 - 627 (2007/10/02)

Reaction of different acetyl compounds with ethyl β, β-bis(methylthio)-α-cyanoacrylate in the presence of powdered potassium hydroxide yields 6-aryl-3-cyano-4-methylthio-2H-pyran-2-ones (1a,b) which react readily with various nucleophiles such as amine, reactive methylene compounds to provide substituted products (2-19) in good yields.
