On November 30, 2020, Abdelkawy, Mahmoud A.; Aly, El-Saied A.; El-Badawi, Mahmoud A.; Itsuno, Shinichi published an article.COA of Formula: C7H10O3 The title of the article was Chitosan-supported cinchona urea: Sustainable organocatalyst for asymmetric Michael reaction. And the article contained the following:
A novel chitosan-supported cinchona urea heterogeneous catalyst was developed for asym. reaction. The catalytic activity of the chitosan-supported organocatalyst was examined in the asym. Michael addition reaction to give chiral adducts in good yields with excellent enantioselectivities (up to 99% ee). The insolubility of the chitosan-supported cinchona urea catalyst facilitated catalyst recovery. The catalyst was easily separated and reused without any loss in catalytic activity. The experimental process involved the reaction of Methyl 2-cyclopentanonecarboxylate(cas: 10472-24-9).COA of Formula: C7H10O3
The Article related to ketoester nitroolefin enantioselective michael reaction, chitosan cinchona urea organocatalyst preparation, General Organic Chemistry: Synthetic Methods and other aspects.COA of Formula: C7H10O3
