摘要：

A formal synthesis of podophyllotoxin has been achieved by means of the well known conjugate addition-alkylation of 5H-furan-2-one, followed by cyclization and controlled epimerizations. This approach represents a useful new route to the 8,7'-trans-stereochemistry of aryltetralin lactones, that in other methodologies requires the opening and reclosure of the lacton ring.
