DOI: 10.1002/ajoc.201700261
Abstract: A straightforward approach to the synthesis of γ-quinolyl carbonyl compounds has been presented via rhodium(III)-catalyzed C(sp3)-H alkylation of 8-methyquinolines with conjugated C＝C multiple bonds. Remarkably, this C(sp3)-H functionalization proceeds under mild reaction conditions, obviates the… read more here.
