Abstract

Rh(III)-catalyzed cascade C–H activation/annulation/lactonization of quinoline-4-ols and alkynes has been reported. A broad range of tetracyclic pyrano[2,3,4-de]quinolines have been prepared in one-step with good functional group tolerance, excellent site selectivity, and high efficiency.
