Abstract: Facile synthesis of polymer-bound Rh(I) phosphine catalyst which is useful for homogeneous asymmetric hydrogenation is described.Polymer bound Pyrphos Rh(I) complex catalyses hydrogenation of prochiral Z--acetamido cinnamic acid to S-N-acetyl phenyl alanine with 76 % ee.  The polymer bound catalyst is cleanly separated from the product by membrane osmodialysis.
