Lewis Acid Catalyzed Addition of Allylsilane to o-Quinonediimides: Formal Diels-Alder Reaction versus Allylation

Abstract

Lewis acid promoted addition of allylsilane to o-qui­nonediimines afforded tetrahydroquinoxaline derivatives or allyl­ated amides, depending on the nature of the substituent on the imine nitrogen.

Key words

o-quinonediimides - allyltriisopropylsilane - Lewis acids­ - tetrahydroquinoxalines - allylated amides
