Copper-Mediated Decarboxylative Coupling of 3-Indoleacetic Acids with Sulfoxonium Ylides for the Synthesis of α-Acetoxyl Ketones

The most convenient and direct method of synthesizing an α-acyloxy ketone is the reaction of a diazo compound with a carboxylic acid via O-H insertion. However, due to the limitations in preparing and storing diazo compounds, the application of this method is restricted. In this study, Cu(OAc)
