acyl substituent across an alkene, oxyacylation of alkenes, using rhodium catalyzed C–O bond activation of an 8-quinolinyl ester is described. Our unsuccessful attempts at intramolecular carboacylation of ketones via C–C bond activation ultimately informed our choice to pursue and develop the intramolecular oxyacylation of alkenes via quinoline-directed C–O bond activation. We provide a full account

GPR120 agonists are provided. These compounds are useful for the treatment of metabolic diseases, including Type II diabetes and diseases associated with poor glycemic control.
chemistry is reported. Both phenol and aromatic or aliphatic acid derivatives could be used under operator-friendly conditions (room temperature, technical solvents, under air). The discovery of the superiority of benziodoxolone-derived hypervalent iodine reagent 3d as an alkyne transfer reagent further expands the rapidly increasing utility of hypervalent iodine reagents in catalysis and is expected

Continuing our investigations into marinenoteodorants, we herein describe several new scaffolds. Among them, 2,3-dihydrobenzofuran-2-carbaldehyde is particularly interesting. The results demonstrate that the seven-membered ring with a ketone functional group of the Calone 1951® family can be replaced by a five-membered ring carrying an aldehyde function. In addition, this work has allowed us to discover
