2-Methylquinoline promoted room-temperature oxidative ring-opening of N-sulfonyl aziridines with DMSO has been developed, providing a mild and convenient method for the synthesis of a variety of different N-sulfonyl protected α-amino aryl ketones. The employment of 2-methylquinoline was crucial for the success of this mild transformation and good to excellent yields could be achieved.

synthesize α-sulfonylamino ketones through the reaction between terminal alkynes and sulfonamides under ambient air using PIDA (diacetoxy iodobenzene). A library of α-sulfonylamino ketone derivatives having a variety of substituents has been synthesized. A plausible reaction pathway has been predicted. This reaction offers a broad substrate scope, metal-free synthesis, excellent regioselectivity, easily
