A novel chiral bisphosphinamidite ligand SpiroNP has been synthesized. The rhodium complex of this ligand has been found to be highly active and enantioselective in the asymmetric hydrogenation of (Z)-2-acetamidoacrylic acid derivatives and α,β-unsaturated carboxylic acid derivatives.

A novel chiral phosphinite 1,2,5,6-di-isopropylidene-3, 4- bis(diphenylphosphino)-D-mannitol was prepared and its rhodium complex was found to be an effective catalyst for the asymmetric hydrogenation of amidoacrylic acid and its derivatives with product ee's ranging from 90% to 97%.
