摘要： A new method for the synthesis of ramosetron hydrochloride, the most wildly used 5-HT3 receptor antagonist, was reported. The intermediate 8 was obtained in a high e.e. value via lipase catalyzed hydrolytic kinetic resolution. Then enantiomerically pure ramosetron hydrochloride was synthesized in two steps with excellent yield (the total yield is 24.6%). The method provides a new environment friendly and atom economy way to synthesize enantiomerically pure ramosetron.
