In the presence of an acidic zwitterion bearing a highly stabilized carbanion, reactions of ω,ω-dialkoxy carbonyl compounds with ketene silyl acetals (KSA) resulted in an unusual molecular transformation; substitution reaction with the KSA at the ketal moiety and simultaneous silylative acetalization of the ketone moiety.
