(R)-(+)-2,2'-Bis(diphenylphosphino)-1,1'-binaphthy is used as a chiral ligand for metal mediated asymmetric catalysis.
Chiral chelating ligand which is the basis of a number of homogeneous catalysts which promote hydrogenation reactions with very high enantiomeric excesses. Rh complexes catalyze the asymmetric hydrogenation of ɑ-acylaminoacrylic acids: J. Am. Chem. Soc., 102, 7932 (1980), and the isomerization of allylamines to chiral enamines: J. Chem. Soc., Chem. Commun., 600 (1982); Synthesis, 665 (1991). Asymmetric hydrogenation of ß-keto esters is achieved with a Ru based catalyst: J. Org. Chem., 57, 6691 (1992). For preparation of a cycloocta-1,5-diene Rh complex and use in enantioselective hydrogenation reaction, see: Org. Synth. Coll., 8, 183 (1993). For a review of the use of Ru BINAP complexes in asymmetric hydrogenation, see: Acta Chem. Scand., 50, 380 (1996).
