Quality Control of Anthrone. I found the field of Chemistry very interesting. Saw the article Design and synthesis of cinchona-based chiral hyperbranched polymers and their application in asymmetric reactions published in 2020, Reprint Addresses Itsuno, S (corresponding author), Toyohashi Univ Technol, Appl Chem & Life Sci, Toyohashi, Aichi 4418580, Japan.. The CAS is 90-44-8. Through research, I have a further understanding and discovery of Anthrone.
Cinchona-based chiral hyperbranched polymers (HBPs) were designed and successfully synthesized via the Mizoroki-Heck (MH) coupling reaction. AB(2) and A(2)B-type chiral monomers were prepared from cinchona squaramide derivatives, where A (vinyl) reacted only with B (iodophenyl) under MH reaction conditions. The chiral HBPs obtained by the MH polymerization contained cinchona squaramide moieties and demonstrated excellent diastereoselectivity and enantioselectivity in asymmetric Michael addition reactions of methyl 2-oxocyclopentanecarboxylate and trans-beta-nitrostyrene. These newly designed HBPs were structurally robust and could be reused for further reaction without losing their catalytic activity. (C) 2020 Elsevier Ltd. All rights reserved.
