A series of N,P-ligands has been prepared, containing a chiral oxazoline ring and as a second chiral unit a bis(N-sulfonylamino)phosphine group embedded in a diazaphospholidine ring or a cyclic phosphite group derived from TADDOL. These modular ligands are readily synthesized from chiral amino alcohols and chiral 1,2-diamines or TADDOLs. Palladium and iridium complexes derived from these ligands were found to be efficient catalysts for enantioselective allylic alkylation and olefin hydrogenation, respectively.

The enantioselective synthesis of sterically congested C 2-symmetric 1,2-di-tert-butyl and 1,2-di-(1-adamantyl) ethylenediamines was successfully achieved starting from the simple heterocycle, 2-imidazolone. An enantioselective synthesis of ste
