Enantioselective Total Synthesis of (-)-Epipodophyllotoxin and (-)-Podophyllotoxin

An enantioselective total synthesis of (-)-epipodophyllotoxin (2) and hence of (-)-podophyllotoxin (1) is described, involving as key steps a conjugate addition on butenolide 13 as the chiral template, a stereoselective aldol condensation on 11a and a ste

TOTAL SYNTHESIS OF (+/-)-PODOPHYLLOTOXIN AND (+/-)-EPIPODOPHYLLOTOXIN.

A novel approach to (+/-)-epipodophyllotoxin (2) and hence also (+/-)-podophyllotoxin (1) is described, involving as a key-step the stereoselective ring closure of the TMS-ester derived from 14a to the tetralin derivative 15 with mesyl chloride.
