Continuous asymmetric Michael addition of ketones to β-nitroolefins over (1R,2R)-(+)-1,2-DPEN-modified sulfonic acid resin

A trifunctional catalyst was successfully prepared by bonding (1R,2R)-(+)-1,2-DPEN to sulfonic acid resin.

Synthesis of Solketal with Catalyst Sulfonic Acid Resin

Solketal is widely used as organic solvent, plasticizer and pharmaceutical intermediates. A synthetic technique for solketal, which is characteristic of being catalyzed by sulfonic acid resin, was developed. Experimental results showed that the suitable synthetic conditions for solketal were as follows: mass ratio of two kinds of raw materials, glycerol to acetone, is 1:20, catalyst DT-851 sulfonic acid resin dosage is 5% (wt, calculated by glycerol), reaction temperature is 58 °C and reaction time is 2 h. The product solketals yield is 95% with purity above 99% under the optimal conditions. This new technique features mild reaction conditions, easy purification, high yield, and less pollution and therefore, it is a kind of clean and green production technique.
