Process for producing a 2H-1,3-thiazolidine, 2H-tetrahydro-1,3-thiazine, or 2H-hexahydro-1,3-thiazepine derivative substituted at the 2 position by a nitromethylene group derivative

摘要

Disclosed is a process for producing a heterocyclic compound having a nitromethylene group as the side chain, of the formula <IMAGE> wherein Y represents a hydrogen atom, a halogen atom or a lower alkyl group, R represents a hydrogen atom, an alkyl group, a cycloalkyl group, an aralkyl group, an alkenyl group, an alkynyl group or an acyl group, and n represents an integer of 2, 3 or 4, which comprises reacting a 2,2,2-trihalo-1-nitroethane compound with a 1-aminoalkanethiol compound or a 1-N-substituted derivative thereof.
