Abstract
Mukaiyama aldol reactions of silyl dienol ether and aldehydes proceeded with high enantioselectivity to give δ-hydroxy-β-keto ester derivatives by using chiral cationic Cr(salen) complex as catalyst in the presence of isopropyl alcohol and base (triethylamine or 2,6-dimethylpyridine).
Key words
Mukaiyama aldol reaction - asymmetric catalysis - Cr(salen) - δ-hydroxy-β-keto ester
