New 6-acetoxy-5,6-dihydro-4H-1,3-oxazinium perchlorates 2 were synthesized by cyclization of N-3-oxoalkylamides 1. The reaction of 2 with sodium hydrosulfide in methanol or dimethylformamide results in the formation of unknown N-3-oxoalkylthioamides 3. New5,6-dihydropyridine-2(1H)-thiones 4 were prepared by cyclization of 3.
