Chemistry of Heterocyclic Compounds Aims and scope

Abstract

The intramolecular cyclization of γ-ketocarboxylic acids and their esters gives 5-alkylsubstituted 3H-thiolen-2-ones and 3H-furan-2-ones. It was shown that reaction occurred at the heterocyclic methylene group and that the conditions under which the reaction took place depended on the nature of the heterocyclic atom.
