Zhang, Baohua; Shi, Lanxiang published the artcile< Asymmetric Henry condensation catalyzed by ionic liquid-supported proline>, HPLC of Formula: 3893-18-3, the main research area is asym Henry condensation proline ionic liquid.

A functionalized ionic liquid-supported proline, 1-methyl-3-{2-[(2S)-pyrrolidine-2-carbonyloxy]-ethyl}-1H-imidazol-3-ium trifluoromethylcarbonate([Promim]CF3CO2), was used to catalyze the Henry condensation reaction of aldehydes with CH3CH2NO2 or CH3NO2. The desired products were obtained in 79%-95% yields, diastereomeric excess and enantiomeric excess was up to 3 : 1 and 85% under relatively mild conditions. [Promim] CF3CO2 could be efficiently recycled six times without the decrease of catalytic activity in the condensation reaction of 4-nitrobenzaldehyde and CH3CH2NO2.
