Peng, Ruixue; Lin, Lili; Zhang, Yuheng; Wu, Wangbin; Lu, Yan; Liu, Xiaohua; Feng, Xiaoming published an article in 2016, the title of the article was The assignment of the configuration for α-hydroxy acid esters using a CEC strategy.Computed Properties of 3976-69-0 And the article contains the following content:
A simple and efficient 1H NMR method for determining the absolute configuration of chiral α-hydroxy acid esters using a competing enantioselective conversion (CEC) strategy was developed. The α-hydroxy acid esters were acylated in the presence of Feng’s chiral N,N’-dioxide-scandium(III) complex, and the faster reaction was identified when one enantiomer of the chiral α-hydroxy acid ester was treated with both enantiomers of the ligand by NMR anal. of the reaction mixture without further purification A mnemonic is presented to aid the assignment of the absolute configuration of the substrates. The experimental process involved the reaction of (R)-Methyl 3-hydroxybutanoate(cas: 3976-69-0).Computed Properties of 3976-69-0
