Synthesis of nitrophenyl-substituted 1,3-thiazoline-2-thiones by oxirane ring opening with several dithiocarbamates
摘要:
Thiazolo-2(3H)-thiones have been prepared by the reaction of triethylamine dithiocarbamates and 4-nitrophenyloxirane via formation of intermediate 2-hydroxy-2-(4-nitrophenyl)ethyldithiocarbamates with simultaneous dehydrogenation of the thiazolidine ring to a thiazoline. It was found that both the basicity of the starting amines and the temperature influenced the course of the reaction.
