Iridium-catalyzed enantioselective hydrogenation of vinyl boronates.

Alexander Paptchikhine1, Pradeep Cheruku, Mattias Engman, Pher G Andersson.   

Abstract

The first Ir-catalyzed asymmetric hydrogenations of vinyl boronates have been performed using low catalyst loadings (0.5 mol%) and pressure (as low as 1 bar). Good selectivities (76-98% ee) were obtained for a range of substrates.
