PROCEDURE

实验过程

A 262 mg quantity of an approximately 50/50 mixture of taxol and cephalomannine was dissolved in 10 mL of ethyl acetate in a 100 mL round bottom flask with magnetic stirring. Then 20 mg of PtO2 was added and the flask was attached to a hydrogenation apparatus. After flushing the flask five times with hydrogen gas, the solution was stirred at room temperature. After 1 hour, the flask was removed from the hydrogenation apparatus and the solution filtered through Celite to remove the catalyst. The resulting solution was evaporated to dryness under vacuum. The result was 262 mg (100%) of a mixture of taxol and dihydrocephalomannine. No further purification was performed and the sample was used as is in the next step.
