The Mukaiyama Aldol Reactions for Congested Ketones Catalyzed by Solid Acid of Tin(IV) Ion-exchanged Montmorillonite

Tin(IV) ion-exchanged montmorillonite (Sn-Mont) was found to be an excellent solid acid catalyst for the Mukaiyama aldol reactions of congested ketones with silicon enolates from ketones as well as esters. It was disclosed that Sn-Mont was far more active than other metal ion- or proton-exchanged mo...
