Synthesis and some transformations of secondary mercaptoethynyl alcohols and ketones of the thiophene series

  • Published:
Chemistry of Heterocyclic Compounds Aims and scope

Abstract

A number of thienylmercaptoethynyl alcohols, which were oxidized to the corresponding ketones, were synthesized via the Iotsich reaction of thiophene-2-aldehyde with mercaptoethynyl ethers. On reaction with hydrazine the ketones undergo intramolecular cyclization to form substituted pyrazoles. The IR spectra of the compounds obtained are discussed.
