Abstract
Several chiral phosphinamide catalysts were prepared from (S)-(+)-Betti Base, (D)-l R,2R-(-)-threo-l-(p-Nitrophenyl)-2-amino-3-triphenyl-methoxypropanol-l and L-Serine respectively.Their application in the asymmetric borane reduction of prochiral ketones was examined.The chiral secondary alcohols were obtained in excellent chemical yields with moderate enantioselective excesses.
