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
