On September 30, 2019, Chhanda, Sadia Afrin; Itsuno, Shinichi published an article.Computed Properties of 144970-30-9 The title of the article was Design and synthesis of chiral hyperbranched polymers containing cinchona squaramide moieties and their catalytic activity in the asymmetric Michael addition reaction. And the article contained the following:
Chiral hyperbranched polymers (HBP) containing cinchona alkaloids were synthesized using a Mizoroki-Heck (MH) coupling polymerization reaction between a cinchona squaramide dimer and tri- or tetra-substituted aromatic iodides. This was a new type of polymeric chiral organocatalyst. We found that the as-obtained chiral HBPs show excellent catalytic activity in the asym. Michael reaction. Almost perfect enantioselectivity (>99% ee) was achieved in the reaction of β-ketoester and trans-β-nitrostyrene. The three-dimensional network structure of the chiral HBPs is structurally robust and can be reused for further reaction without any loss in their catalytic activity. The experimental process involved the reaction of 1,3,5,7-Tetrakis(4-iodophenyl)adamantane(cas: 144970-30-9).Computed Properties of 144970-30-9
