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 regioselectivity asymmetric hydrogenation of quinoxalines, benzofurans, thiophenes, indolizines, isocoumarins and many other heterocycles.
Product can be used with our benchtop hydrogen generator, H-Genie Lite (Z744083)

A novel and practical chiral ruthenium-NHC-diamine system is disclosed for the enantioselective hydrogenation of isocoumarins, which provides a new concept to apply (chiral) NHC ligands in asymmetric catalysis. A variety of optically active 3-substituted 3,4-dihydroisocoumarins were obtained in excellent enantioselectivities

An efficient synthesis of optically active 4-substituted 2-oxazolidinones by the ruthenium(ii)-NHC-catalysed asymmetric hydrogenation of 2-oxazolones was developed. Excellent enantioselectivities (up to 96% ee) and yields (up to 99%) were obtained for a variety of substrates, bearing a range of functional
