Abstract

Abstract An efficient one-pot three-component method for the synthesis of a variety of 2- thioxo-2H-thiopyrans has been described. Fairly good yields are obtained by cyclization reactions of arylidenemalononitriles, derived in situ from ketones and malononitrile, with carbon disulfide in the presence of a base in the ionic liquid 1-butyl-3-methylimidazolium bromide as reaction medium.[Supplemental materials are available for this article.
