Phytochemical medicinal agents. A quinone-based route to pterocarpins.

George A Kraus1, Jingqiang Wei.   

Abstract

The synthesis of 6,9 di-demethoxy kushecarpin A has been achieved by the coupling of a benzofuran anion with a quinone monoketal followed by a regioselective cyclization and a stereoselective hydrogenation reaction.
