On February 28, 2011, de Lange, Ben; Hyett, David J.; Maas, Peter J. D.; Mink, Daniel; van Assema, Friso B. J.; Sereinig, Natascha; de Vries, Andre H. M.; de Vries, Johannes G. published an article.Synthetic Route of 79815-20-6 The title of the article was Asymmetric Synthesis of (S)-2-Indolinecarboxylic Acid by Combining Biocatalysis and Homogeneous Catalysis. And the article contained the following:
The use of a combination of biocatalysis and homogeneous catalysis led to a very short synthesis route to enantiopure (S)-2-indolinecarboxylic acid. Thus, reacting 2-ClC6H4CHO with Ac2O/NaOAc gave 2-ClC6H4CH:CHCO2H in 55% yield. The latter compound was treated with phenylalanine ammonia lyase to give (S)-2-ClC6H4CH2CH(NH2)CO2H (I), that, upon addition of CuCl/H2O, produced 77% of the title compound Alternatively, treating 2-ClC6H4CH:CH(NHCOMe)CO2H with [Rh(cod)2]BF4/MonoPhos/H2CH2Cl2 gave the reduced compound which was then converted into I and taken on to the final compound as stated above. The experimental process involved the reaction of H-Idc-OH(cas: 79815-20-6).Synthetic Route of 79815-20-6
