Abstract

Acylation of 4-substituted 4H-thieno[3,2-b]pyrrole-5-carbohydrazides with chloroacetyl chloride, dichloroacetyl chloride, and methacryloyl chloride afforded the corresponding mixed bis-acylhydrazines. Likewise, the reaction of 4-benzyl-4H-thieno[3,2-b]pyrrole-5-carbonyl chloride with ethyl 5-(hydrazinocarbonyl)pyridine-2-carboxylate gave ethyl 5-[2-(4-benzyl-4H-thieno[3,2-b]pyrrole-5-carbonyl)hydrazine-1-carbonyl]pyridine-2-carboxylate.

摘要

用氯乙酰氯，二氯乙酰氯和甲基丙烯酰氯酰化4-取代的4 H-噻吩并[3,2 - b ]吡咯-5-碳酰肼，得到相应的混合双酰基肼。同样，4-苄基-4 H-噻吩并[3,2 - b ]吡咯-5-羰基氯与5-（肼基羰基）吡啶-2-羧酸乙酯的反应得到5- [2-（4-苄基- 4 H-噻吩并[3，2 - b ]吡咯-5-羰基）肼-1-羰基吡啶-2-羧酸酯。
