Chiral cationic diamidophosphite: Novel effective ligand for Pd-catalysed enantio selective allylic substitution
Novel diamidophosphite ligand bearing alkylammomium fragment was prepared by a one-step phosphorylation of a quaternised aminoalcohol. The ionic ligand demonstrated high enantioselectivity in the Pd-catalysed allylic substitution of 1,3-diphenylallyl acetate (up to 99% ee). (c) 2006 Elsevier B.V. All rights reserved.
