An efficient selective synthesis of methyl dithienyl-glycolates has been developed. The interest of this two steps protocol resides in the possibility of synthesized either methyl 2,2-dithienyl glycolate – the target intermediate for the preparation of anticholinergic agents – or its regio-isomer methyl 2,3-dithienyl glycolate – the most critical precursor of anticholinergic drug impurity.
已开发出二噻吩基乙醇酸甲酯的有效选择性合成。这两个步骤协议的兴趣在于合成 2,2-二噻吩基乙醇酸甲酯(制备抗胆碱能药物的目标中间体)或其区域异构体 2,3-二噻吩基乙醇酸甲酯(最关键的前体)的可能性。抗胆碱能药物杂质。
