| Abstract: | In aqueous micelles formed from the chiral surfactants N-dodecyl-N, N-dimethylephedrine bromide 1 a and N-hexadecyl-N, N-dimethyl ephedrine bromide 1 b, a series of op-tical active products were obtained by Michael addition of nitromethane or thiophenol tochalcones using piperidine as catalyst, the enantiomer excess was up to 17%. Mcanwhile,we have found that micellar system can accelerate the Michael reaction. |
