G protein coupled receptor 40(GPR40) is a potential target for treatment of type 2 diabetes. Herein, the well-known GPR40 agonist TAK-875(compound 1) was synthesized as a positive control. Besides, an epimeric mixture 11,which was the sulfoxide analog of compound 1 was also synthesized. The following chiral HPLC separation of 11 led to optically pure compounds 12(S,S, 100.0% de) and 13(R,S, 100.0% de), of which the absolute configurations were determined by circular dichroism spectra analysis. In vitro biol...
