Lewis acid catalyzed Diels-Alder reactions of 1,2-naphthoquinones.

Danny M Gelman1, Craig M Forsyth, Patrick Perlmutter.   

Abstract

The use of BF(3) x OEt(2) catalysis in Diels-Alder reactions of 3,4-unsubstituted 1,2-naphthoquinones provides direct access to cis-tetrahydrophenanthrene derivatives in good to excellent yields (66-99%) without rapid adduct aromatization commonly associated with corresponding thermal processes.
