Abstract
The aldol reaction of silyl enolates with aldehydes or acetals using a lanthanide trifluoromethanesulfonate as catalyst smoothly proceed in organic solvents to afford the corresponding aldol-type adducts in high yields. The catalyst can be easily recovered after the reaction is completed, and yields of the 2nd run of the catalyst are comparable to those of the 1st run.Keywords
