Abstrakt: A direct asymmetric aldol reaction of aldehydes and acetone catalyzed by L-Pro- L-Trp was performed in β-caprolactamquaternary ammonium salt coordination ionic liquid media in the presence of N-methylmorpholine (NMM) in high yield and with good enantioselectivity. The approach has the advantages of simple product isolation, and reusable catalyst and coordination ion liquids. [ABSTRACT FROM AUTHOR]
