C. Pasquier et al., ENANTIOSELECTIVE HYDROGENATION OF FUNCTIONALIZED KETONES - SYNTHESIS AND APPLICATION OF NEW CHIRAL AMINOPHOSPHINE-PHOSPHINITE LIGANDS, Synlett, (10), 1998, pp. 1162
The chiral new aminophosphine-phosphinites (AMPP's 1-7) have been synt
hesised and applied successfully in the enantioselective hydrogenation
of dihydro-4,4-dimethyl-2,3-furandione 8, N-benzylbenzoylformamide 9,
and ethylpyruvate 10 providing the hydroxy products in up to 97, 95,
and 80% ee, respectively.
