✦ Synopsis

Aromatic (2c and 2d) and aliphatic (2a and 2b) anionic surfactants were employed in Sc(OTf) 3 -catalyzed aldol reactions of some labile silyl enol ethers (3a and 3b) with aromatic aldehydes in water. The results indicated that the aromatic surfactants have a better ability to inhibit the hydrolysis of labile silyl enol ethers and promote the aldol reaction, leading to higher yields of aldol adducts.

Scandium triflate (Sc(OTf)3)-catalyzed aldol reactions of silyl enol ethers with aldehydes were successfully carried out in micellar systems. While the reactions proceeded sluggishly in water, remarkable enhancement of the reactivity was observed in the presence of a small amount of a surfactant. In
