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.

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

A novel approach to (+/-)-epipodophyllotoxin (2c) and hence also to (+/-)-podophyllotoxin (1c) is described, involving as a key-step the stereoselective ring closure of the TMS-ester derived from 17a to the tetralin derivative 30c with mesyl chloride.
