the presence of a catalytic amount of trityl salts, such as TrOTf, TrSbCl6, TrPF6, TrSnCl5, etc., silyl enol ethers react with aldehydes to give the corresponding aldols in good yields. The preferential formations of erythro or threo aldols become possible by the suitable choice of the counter anions of these trityl salts and the substituents on silicon of the enolates.
