CAMPTOTHECIN COMPOUND CONTAINING STABLE 7-MEMBERED LACTONE RING, PREPARATION METHOD AND USE

Provided are a camptothecin compound containing 7-membered lactone ring, as shown in general formula I, and pharmaceutically acceptable salt thereof, as well as the preparation method and use thereof. In general formula I, R1 is H, a C1～C3 alky

Total synthesis of camptothecin and SN-38

A new practical and concise total synthesis of enantiopure camptothecin and SN-38 (14% overall yield, 99.9% ee and 99.9% purity) was described, starting from inexpensive and readily available materials. The development of column chromatography-free purification was achieved in all steps, which offers an economic industrial process to the camptothecin-family alkaloids.
