Use of Trichlorosilyl Enolates and Chiral Lewis Bases

Aldehyde trichlorosilyl enolates as well as ketone trichlorosilyl enolates are useful 

67) [175]. The dimeric l,l -binaphthyl-2,2 -diamine-derived phosphoramide 81 effectively catalyzes the asymmetric process, occasionally with high stereoselectivity. The adducts, / -hydroxyaldehydes, can be isolated as the stable dimethyl acetals by treatment of the reaction mixture with MeOH.
