Disclosed is a process for producing a heterocyclic compound having a nitromethylene group as the side chain, of the formula:
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.
本发明公开了一种以硝基亚甲基为侧链的杂环化合物的生产工艺,其式如下
其中 Y 代表氢原子、卤素原子或低级烷基,R 代表氢原子、烷基、环烷基、芳基、烯基、炔基或酰基,n 代表 2、3 或 4 的整数,该工艺包括使 2,2,2-三卤-1-硝基乙烷化合物与 1-氨基烷硫醇化合物或其 1-N-取代衍生物反应。
