Technical Notes:

1. The DUPHOS family of catalysts is highly efficient for the asymmetric hydrogenation of various substituted acetamidoacrylates and enol acetates yielding products of high enantiomeric excesses. Efficient ligand for the asymmetric hydrogenation of

tetrasubstituted enamides

2. Forms superior catalysts for asymmetric reductive aminations.

3.Catalyst used for the asymmetric hydrogenation of e nol phosphonates.

4.A novel enantioselective synthesis of ß amino alcohols and 1 ,2-diamines

5.L igand for the catalytic asymmetric 4+ 1 cycloaddition of vinylallenes with co.

6.L igand for the R h- c a ta lyzed asymmetric enyne cycloisomerizatio n.

7.Catalytic e nantioselective addition of dialkylzinc to N-Diphenylphos phinoylimines.

8.Palladium catalyzed asymmetric phosphination.
