N-3-oxoalkylamides and -thioamides in synthesis of heterocyclic compounds. 2. Synthesis of 6-acetoxy-5,6-dihydro-4H-1,3-oxazinium perchlorates. New method of preparation of N-3-oxoalkylthioamides

Abstract

Previously unknown 6-acetoxy-5,6-dihydro-4H-1,3-oxazinium perchlorates were obtained by reacting N-3-oxoalkylamides with perchloric acid in acetic anhydride. It was found that the reaction of 6-acetoxy-5,6-dihydro-4H-1,3-oxazinium perchlorates with sodium hydrosulfide yields N-3-oxoalkylthioamides.
