Mukaiyamaaldolreactions using ketene silyl acetals with various aldehydes proceed smoothly in ionicliquids to afford the corresponding aldol products in moderate yields.
Lithium acetate catalyzed aldolreactionbetweentrimethylsilylenolates and aldehydes in a DMF–H2O (50:1) solvent proceeded smoothly to afford the corresponding aldols in good to high yields. It is noted that trimethylsilylenolates derived from carboxylic esters behaved as excellent nucleophiles in the above reaction.
