Org Biomol Chem. 2007 Oct 7;5(19):3201-6. doi: 10.1039/b710370k. Epub 2007 Aug 31.

Abstract

A concise, seven step synthesis of the aryl tetralin lignan lactone epi-picropodophyllin from piperonal is described. The key steps are a silene diene Diels-Alder reaction and the Hosomi-Sakurai reaction of the resultant silacyclohexene.
