Abstract: The aldol condensation of p- nitrobenzaldehyde with acetone catalyzed by metal ( Ⅱ )-ephedrine-BB-CDand metal ( Ⅱ )-N-methylephedrine-BB-CDsystems was carried out under mild and neutral conditions to afford an enantiomorphous excess aldol type product, 4-hydroxy-4-(4-nitro-phenyl)-2-butanone. The highest yield of the aldol type product is 82. 8%. The highest specific rotation [a]D15 is -6.7.

Key words: Transition metal (Ⅱ) coordination compounds, Aldol condensation, Enantiomer
