A novel and simple protocol has been developed for the regioselective sulfonylation of quinolone N-oxides at their C-2 postition. This method features with a simple system, high efficiency, environmental friendliness, and metal-free conditions. Aliphatic and aryl sulfonyl hydrazides smoothly undergo sulfonylation with quinoline N-oxides in good yields.
