Materials and methods for preparing (S)-(+)-3-(aminomethyl)-5-methyl~hexanoic acid and structurally related compounds via enantioselective hydrogenation of prochiral olefins are disclosed. The methods employ novel chiral catalysts, which include C1-symmetric bisphosphine ligands bound to transition metals.
L'invention concerne des matériaux et procédés de préparation d'acide (S)-(+)-3-(aminométhyl)-5-méthyle-hexanoïque et des composés structurellement liés par hydrogénation énantiosélective d'oliéfines prochirales. Ces procédés emploient de nouveaux catalyseurs chiraux qui contiennent des ligands de biosphosphine C¿1?-symétrique liés aux métaux de transition.
