摘要
以2,4-二氯-5-氟苯乙酮为原料,经草酰化,醚化,胺化,环合,水解,脱碳等反应提出一条合成环丙沙星重要中间体环丙羧酸的新方法,反应条件温和,操作容易控制。并在此过程中制备了四种新化合物。
The research put forward a new synthetic method of cyclopropyl carboxylic acid, theimportant intermediate of ciprofloxacin. The reaction was started with 2,4-dichloro-5-fluoroacetophenone, via oxalylation, etherificahon, alnination, cyclization, hydrolysis and decarbonylation,The reaction temperature was moderate and the operation was easily controlled. Addtional, four newcompounds were synthesized by the suggested method.
