C-Acylation of rhodanine derivatives

  • Published:
Chemistry of Heterocyclic Compounds Aims and scope

Abstract

The corresponding 5-aroyl derivatives were obtained by reaction of aromatic carboxylic acid chlorides with 3-ethylrhodanine, and their chemical and physicochemical properties were studied. It is shown that they are completely enolized and stabilized by intramolecular hydrogen bonding; the side-chain carbonyl group undergoes enolization. Methylation with diazomethane gives O-ethers α-methoxyarylidene derivatives of 3-ethylrhodanine and S-ethers, which exist as dipolar ions.
