Abstract
Sulfonyl chloride has been rarely used as Cl source in transition metal-catalyzed C−H functionalizations. We report the unprecedented copper-catalyzed remote C5-chlorination of substituted 8-amidoquinolines with sulfonyl chloride under 1 atm oxygen. 10 sulfonyl chlorides and 15 substituted 8-amidoquinolines were tested, generating moderate to high yields. The catalytic system showed high regio-selectivity, as well as good functional group tolerance.
