A procedure was proposed for regioselective acylation of methyl 2-methyl-4H-thieno[3,2-b]-pyrrole-5-carboxylate with 2-(3-indolyl)-2-oxoacetyl chloride. Reactions of the resulting methyl 6-[2-(3-indolyl)-1,2-dioxoethyl]-2-methyl-4H-thieno[3,2-b]pyrrole-5-carboxylate with aromatic aldehydes and ammonium acetate in acetic acid afforded the corresponding methyl 6-[2-aryl-4-(3-indolyl)imidazol-5-yl]-2-methyl-4H-thieno[3,2-b]pyrrole-5-carboxylates. The structure of methyl 6-[2-(4-chlorophenyl)-4-(3-indolyl)imidazol-5-yl]-2-methyl-4H-thieno[3,2-b]pyrrole-5-carboxylate was studied by X-ray analysis.
提出了一种用于选择性乙酰化甲基2-甲基-4H-噻吩[3,2-b]吡咯-5-羧酸酯与2-(3-吲哚基)-2-氧代乙酰氯的程序。将所得甲基6-[2-(3-吲哚基)-1,2-二氧代乙基]-2-甲基-4H-噻吩[3,2-b]吡咯-5-羧酸酯与芳香醛和乙酸铵在乙酸中反应,得到了相应的甲基6-[2-芳基-4-(3-吲哚基)咪唑-5-基]-2-甲基-4H-噻吩[3,2-b]吡咯-5-羧酸酯。通过X射线分析研究了甲基6-[2-(4-氯苯基)-4-(3-吲哚基)咪唑-5-基]-2-甲基-4H-噻吩[3,2-b]吡咯-5-羧酸酯的结构。
