Imino aldol reaction of ketene silyl acetals with imines proceeds smoothly to give beta-amino esters in good yields under the influence of a cation-exchange resin in ethanol, and the work-up of the reaction consists only of a simple filtration followed by concentration of the crude mixture and purification.
