Recently I am researching about QUATERNARY AMMONIUM POLYMERS; MICHAEL ADDITION; CHIRAL POLYMERS; ORGANOCATALYSTS; ARYL, Saw an article supported by the . Product Details of 90-44-8. Published in WILEY-V C H VERLAG GMBH in WEINHEIM ,Authors: Abdelkawy, MA; Aly, EA; El-Badawi, MA; Itsuno, S. The CAS is 90-44-8. Through research, I have a further understanding and discovery of Anthrone
Chiral polyureas of cinchona alkaloids were synthesized via repetitive Mizoroki-Heck (MH) coupling reaction. The Pd-catalyzed polycondensation of cinchona urea dimers6and aromatic diiodide7afforded the chiral polyureas (P1-P4). The catalytic activity of the chiral polymers was subsequently investigated. The asymmetric Michael addition of ketoesters to nitroolefins was successfully catalyzed by the polymeric organocatalysts (P1-P4) to give the corresponding Michael adducts with high catalytic activities and excellent enantionselectivities (up to >99% ee). The polymeric catalysts were insoluble in commonly used organic solvents. They were easily recovered and reused several times without any loss of the catalytic activity.
