On June 30, 2022, Farhadur Rahman, Mohammad; Yangyuayang, Chouthor; Fujisawa, Ikuhide; Haraguchi, Naoki; Itsuno, Shinichi published an article.Recommanded Product: Methyl 2-cyclopentanonecarboxylate The title of the article was C5′-Nitrated Cinchona Catalysts for Asymmetric Michael Addition Reaction. And the article contained the following:
C5′-Nitro-dihydroquinine (Q1), prepared from dihydroquinine (HQ), exhibited high catalytic activity in an asym. Michael reaction. The nitro group at the C5′ position of Q1 was vertically fixed to the quinoline ring, as confirmed by X-ray crystallog. Q1 exerted a high level of asym. induction, superior to that of the non-nitrated HQ catalyst. The experimental process involved the reaction of Methyl 2-cyclopentanonecarboxylate(cas: 10472-24-9).Recommanded Product: Methyl 2-cyclopentanonecarboxylate
