stereoselective reactions catalyzed by Brønsted and Lewis acids. Gold(III) chloride and bismuth(III) triflate were found to be especially efficient as catalysts, showing kinetically controlled differentiation in the reactivity of diastereomeric α-substituted benzyl alcohols. Applications to therapeutically relevant syn- and anti- 2-amino-1,1-diarylalkanes are projected.
