The configuration of (+)-2,3-diphenylpropanoic acid has been related to that of (R)-(–)-2-phenylpropanoic acid by converting both acids into (+)-1,2-diphenylpropane. The configuration of (+)-2-methyl-3-phenylpropanoic acid has been related to that of (R)-(+)-3-phenyl-2-(2-thienyl)propanoic acid by converting both acids into (+)-2-methyl-1-phenylhexane. (R)-(+)-3-Phenyl-2-(2-thienyl)propanoic acid has

2,3-Diaryl propanoic acids are important structures as a result of their widespread presence in numerous bioactive compounds. However, the limitations of existing synthetic techniques include the requirement for costly catalysts and limited substrates. Here, we developed a novel electroreductive arylcarboxylation of alkenes with CO2 based on a radical–polar crossover pathway assisted by easily accessible
2,3-二芳基丙酸是重要的结构,因为它们广泛存在于许多生物活性化合物中。然而,现有合成技术的局限性包括需要昂贵的催化剂和有限的底物。在这里,我们开发了一种新型的烯烃与 CO 2的电还原芳基羧化反应,该反应基于自由基-极性交叉途径,并辅以易于获得的对苯二甲酸二甲酯作为还原介体。该方法将为2,3-二芳基丙酸的合成提供有效的策略。
