Significance
Sc(III)-doped USY zeolite [Sc(III)-USY] was prepared by the treatment of H-USY with Sc(OTf)3 under N2 stream at 450 ˚C for two days. Sc(III)-USY (1 or 10 mol% Sc) catalyzed the Mukaiyama aldol reaction of silyl enol ethers 1 with aldehydes 2 at room temperature to give the corresponding aldol adducts 3 in up to 100% yield (20 examples).
