A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, HPLC of Formula: C20H14O2, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 18531-94-7, Name is (R)-[1,1′-Binaphthalene]-2,2′-diol, molecular formula is C20H14O2. In a Article, authors is Li, Hong，once mentioned of 18531-94-7
(Chemical Equation Presented) Direct asymmetric aldol reaction of aryl ketones with aryl aldehydes catalyzed by chiral metal complex is reported for the first time herein. Two novel semicrown chiral ligands 1a and 1b were synthesized from (S)- and (R)-BINOL, respectively, and then employed to catalyze the direct asymmetric aldol addition of aryl ketones to aryl aldehydes. Introduced with 2.0 equiv of diethylzinc, 1b had higher enantioselectivity than 1a. Up to 97% yield and up to 80% enantioselectivity were achieved.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 18531-94-7, help many people in the next few years.HPLC of Formula: C20H14O2
