Novel Aerobic Oxidation of Primary Sulfones to Carboxylic Acids
摘要:
Primary alkyl aryl sulfones are converted to the corresponding carboxylic acids in fair to excellent yield through double deprotonation and exposure to atmospheric oxygen. The methodology allows for the convenient synthesis of C-13 labeled carboxylic acids.

The use of aminals as precursors for iminium ions has been limited to methylene derivatives, thus hampering its broader use. By employing electron-deficient iminium ions an obvious hurdle of the methodology is overcome, whilst generating highly desirable motifs. This broad concept is highlighted by the late-stage amination of quinine into a biologically interesting new analogue.

gold-catalyzed Heckreaction facilitated by the ligand-enabled Au(I)/Au(III) redox catalysis. The elementary organometallic steps such as migratory insertion and β-hydride elimination have been realized in the catalytic fashion for the first time in gold chemistry. The present methodology not only overcomes the limitations of previously known transition metal-catalyzed Heckreactions such as the requirement

A gold-catalyzed chain-walking process is presented herein by employing a ligand-enabled Au(I)/Au(III) redox catalysis. This process is harnessed to develop a novel gold-catalyzed annulation reaction of alkenes with iodoarenes by leveraging the interplay of chain-walking and π-activation reactivity mode.
