Sun, Xianfeng published the artcileMatching and mismatching effects of hybrid chiral biaxial bisphosphine ligands in enantioselective hydrogenation of ketoesters, Recommanded Product: (R)-[1,1′-Binaphthalene]-2,2′-diyl bis(trifluoromethanesulfonate), the publication is Chemistry – A European Journal (2009), 15(30), 7302-7305, S7302/1-S7302/10, database is CAplus and MEDLINE.
Three biaxial diphosphine ligands were synthesized. Their catalytic use in asym. hydrogenation of ketoesters to hydroxy esters were discussed. It was found that compound I together with [Ru(benzene)Cl2]2 was the best catalyst to promote the asym. hydrogenation of α-ketoesters to α-hydroxyesters.
Chemistry – A European Journal published new progress about 126613-06-7. 126613-06-7 belongs to esters-buliding-blocks, auxiliary class Chiral Diphenols, name is (R)-[1,1′-Binaphthalene]-2,2′-diyl bis(trifluoromethanesulfonate), and the molecular formula is C9H10N2O, Recommanded Product: (R)-[1,1′-Binaphthalene]-2,2′-diyl bis(trifluoromethanesulfonate).
