Recently I am researching about ENANTIOSELECTIVE ACYL TRANSFER; ACHIRAL CARBOXYLIC-ACIDS; ASYMMETRIC ESTERIFICATION; PIVALIC ANHYDRIDE; DIPHENYLACETIC ACID; LIPASE; ALCOHOLS, Saw an article supported by the . Published in WILEY-V C H VERLAG GMBH in WEINHEIM ,Authors: Ichimura, T; Kishida, R; Nakata, K. The CAS is 93-97-0. Through research, I have a further understanding and discovery of Benzoic anhydride. Formula: C14H10O3
Non-enzymatic acylative kinetic resolution of racemic 2,2-dimethyl-substituted nitroaldol (Henry) adducts was achieved using cyclohexanecarboxylic anhydride in the presence of chiral guanidine catalyst. The systematic evaluation of the substituents on the aromatic rings of the substrates were conducted to clarify the influence of the substituents. The reaction was smoothly proceeded with moderate to good s-values, regardless of the kinds of the substituents. Based on the absolute configuration of the resulted product, the transition state of the reaction was predicted, and it was important the interaction between the nitro group on the substrate and the cation face of the acyl-guanidium intermediate to determine the direction of the substrate.
Formula: C14H10O3. About Benzoic anhydride, If you have any questions, you can contact Ichimura, T; Kishida, R; Nakata, K or concate me.
