structures (3-aminopyrroline-2-thiones and 3-iminopyrrolidine-2-thiones). The latter was reacted with chloroacetic acid, ethyl chloroacetate, chloroacetamide and 2,3-dichloro-l,4-naphthoquinone to give the corresponding pyrrolothiazines derivatives. On using phenylisocyanate or p-chlorobenzoyl chloride, the corresponding pyrrolothiazole derivatives could be isolated. Replacement of chalcones by maleimides furnished
摘要 氰硫甲酰胺与查耳酮相互作用得到 3-氨基-2-巯基吡咯,其具有互变异构结构(3-氨基吡咯啉-2-硫酮和 3-亚氨基吡咯烷-2-硫酮)。后者与氯乙酸、氯乙酸乙酯、氯乙酰胺和2,3-二氯-1,4-萘醌反应得到相应的吡咯噻嗪衍生物。在使用异氰酸苯酯或对氯苯甲酰氯时,可以分离出相应的吡咯并噻唑衍生物。用马来酰亚胺代替查耳酮提供吡咯并吡咯烷二酮。
