The trichlorosilylenolate of a chiral methyl ketone bearing an oxygen substituent (OTBS) on the β-position undergoes highly diastereoselective aldoladdition to a variety of achiral aldehydes in good yield. The stereochemical course of the reaction is primarily controlled by the configuration of the chiral phosphoramide which serves as an effective catalyst for this transformation.
