Abstract

A palladium-catalyzed synthesis of enantiopure [1,1′-binaphthalene]-2,2′-dicarbonitriles from BINOL-bistriflates and zinc cyanide is reported. This cross-coupling reaction employs a 0.1–5 mol% catalyst loading, and is scalable and stereospecific. The synthetic applications of this reaction are demonstrated by product derivatizations and the synthesis of [1,1′-binaphthalene]-2,2′-bisoxazolines (BOXAX).
