✦ Synopsis

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 these systems, versatile carboncarbon bond-forming reactions proceeded in water without using any organic solvents.
