An iodine(III)-mediated, group-selective oxidative rearrangement of [small beta],[small beta]-diarylenamines to [small alpha]-amino ketones has been accomplished with excellent yield. The developed reaction involves the initial oxidation of enamine to [small alpha]-acyloxyimine intermediate and concomitant...

synthetic route to a wide range of 2-alkoxyaryl-2-aryl enamines is developed from Rh-catalyzed alkoxyarylation of N-sulfonyl-4-aryl-1,2,3-triazoles with aryl ethers via the elimination of nitrogen molecule. In addition, 2-alkoxyaryl-2-aryl enamines are prepared via tandem Cu-catalyzed cycloaddition and Rh-catalyzed alkoxyarylation starting from alkynes, N-sulfonyl azides, and aryl ethers in one-pot.
