Description

Application

(R,R)-SINpEt⋅HBF4 is a chiral NHC ligand developed in the Glorius Lab for use in Ru(II) catalyzed enantioselective hydrogenations. It has been employed for the regioselective asymmetric hydrogenation of quinoxalines, benzofurans, thiophenes, indolizines, isocoumarins and many other heterocycles.
