α-Methyl-α-(trifluoromethylphenyl)malonic acids have been incubated with Alcaligenesbronchisepticus to afford optically active α-arylpropionic acids. Generally, the chemical and optical yields of the reaction products were higher when the substituents on the aromatic ring were strongly electron-withdrawing. Decarboxylation of α-fluoro-α- phenylmalonic acid with the aid of the same bacterium afforded
已经将α-甲基-α-(三氟甲基苯基)丙二酸与支气管曲霉(Alcaligenes bronchisepticus)一起温育,以提供旋光性α-芳基丙酸。通常,当芳环上的取代基强烈吸电子时,反应产物的化学和光学产率较高。在相同细菌的帮助下,α-氟代-α-苯基丙二酸的脱羧得到光学活性的α-氟代-α-苯基乙酸。
