Asymmetric Reduction of Prochiral Ketones in Aqueous Micelles of Chiral Surfactants (-)-Trialkylmskthylammcnium Bromides

Abstract
Prochiral Ketones were reduced by NaBH4 in aqueous micelles formed from chiral surfactants (-)-N-alkyl-N,N-dimethylmenthylammonium bromides, giving optically active alcohols with enantioselectivity up to 17.7%.
