Synthesis of retrochinensin; a new naturally occurring 4-aryl-2,3-naphthalide lignan

Abstract
2,3-Dichloro-5,6-dicyanobenzoquinone-induced oxidative cyclization of suchilactone (I) afforded retrochinensin (II), a new naturally occurring 4-aryl-2,3-naphthalide lignan, in high yield; treatment of (I) with N-bromosuccimide on the other hand, afforded justicidin B (IV) in high yield.
