Chiral Anionic Surfactants for Asymmetric Mukaiyama Aldol-Type Reaction in Water

Abstract
Sulfonate derivatives of chiral 1,1′-binaphthol were used as chiral anionic surfactants in asymmetric aldol-type reaction in water to give aldol adducts with moderate to good diastereo- and enantioselectivities; Ga(OTf)3 and Cu(OTf)2 were better than Sc(OTf)3 as Lewis acid catalysts.
