Abstract:
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.
