We have undertaken a synthesis of this substance as part of a broader program in the area of biologically active macrocyclic natural products. One attractive approach to the synthesis of maytansine involves the introduction of chiraltty at carbons 3, 4, 5, 10, and 9 after formation of the macro ring

The iodo lactone I, which has been used as a key intermediate for the synthesis of the six natural primary prostaglandins, is readily available by a synthetic process in which the average yield per step is 95% (l-4). Although the A prostaglandins can be derived from the primary E prostaglandins by d

An enantioselective route for the total synthesis of forskolin, a potent activator of adenylate cyclase, has been developed which is based on reduction of dienone 3 to the (S)-alcohol4 and conversion in two steps to tricyclic lactone 9, obtained in optically pure form simply by recrystallization. A
