Selective remote C–H sulfonylation of aminoquinolines with arylsulfonyl chlorides via copper catalysis

This is the authors' abstract. We don't add key points for this paper.

Copper-catalysed direct C-H bond sulfonylation of aminoquinolines using commercially available and inexpensive arylsulfonyl chlorides as the sulfonylation reagents is described. The reactions took place exclusively at the C5-H position of the quinoline rings and tolerated a wide spectrum of functional groups. Moreover, synthetic transformations of the sulfonylated products led to useful compounds.
