We present new ureaphosphine ligands that coordinate in a P,O-bidentate fashion to rhodium(I). The ureaphosphine-Rh(I)-complexes were effectively used in the asymmetric hydrogenation of cyclic enamides giving high conversions and enantioselectivity.
Protic aminophosphines with multiple chiral centers were synthesized in good yields and high purity by the nucleophilic ring-opening of N-protected cyclic sulfamidates with metal phosphides, followed by hydrolysis and deprotection. This synthetic approach is clean, scalable, and high yielding. The method provides an efficient alternative route for the synthesis of chiral aminophosphines.

The present application is directed to i) a method for synthesizing aminophosphine (P,N) and phosphine-aminophosphine (P,N,P) ligands, ii) the use of such ligands in the preparation of metal complexes as hydrogenation catalysts, and iii) aminophosphine (P,N) and phosphine-aminophosphine (P,N,P) ligands of various structures. In particular, the methods in i) involve reacting a protected tertiary amine of formula (I) with a metal phosphide of the formula Y—PR8R9 to afford an aminophosphine of formula (II), which can then be optionally further reacted with a phosphine of the formula (III) to afford the phosphine-aminophosphine of formula (IV).
