摘要
2-溴-3-甲基噻吩的格氏试剂与氯甲酸甲酯加成后“一锅”与环丙基溴化镁加成制得环丙基二(3-甲基-2-噻吩基)-甲醇,开环后与(R)-(-)-3-哌啶甲酸乙酯经缩合、水解和成盐反应制得盐酸噻加宾,总收率41%。
Tiagabine hydrochloride was synthesized from 2-bromo-3-methylthiophene Grignard reagent by tandem addition with methyl chloroformate and cyclopropylmagnesium bromide to give cyclopropyl-bis (3-methylthiophen-2-yl) - methanol, which underwent ring opening and condensed with ethyl (R) - (一) -piperidine-3-carboxylate, hydrolysis and HCl salt formation in 41% overall yield.
