Herein, we describe a synthetic approach for arylation that exploits the in situ formation and reaction of an unsymmetrical diaryliodonium salt. In this way, aryl iodides are used as reagents in a metal‐free reaction with phenols, and a trimethoxyphenyl (TMP) group is used as a “dummy” group to facilitate transfer of a wide range of aryl moieties. The scope of aryl electrophiles and phenol nucleophiles

The present invention generally relates to substituted heterocyclic derivatives (the compounds of Formula (I)), processes for their preparation, pharmaceutical compositions containing said compounds, their use as G-protein coupled receptor (GPR) agonists, particularly as GPR40 agonists and methods of using these compounds in the treatment of GPR40 mediated diseases or conditions such as Type 2 diabetes, obesity, dyslipidemia, hyperlipidemia, hypercholesterolemia, and hypertriglyceridemia.
High reactivity of trimethoxyphenyl (TMP)-iodonium(III) acetate for phenol O-arylation was achieved. It was first determined that the TMP ligand and acetate anion cooperatively enhance the electrophilic reactivity toward phenol oxygen atoms. The proposed method provides access to various diaryl ethers in significantly higher yields than the previously reported techniques. Various functional groups
