An Rh(III)-catalyzed C–Hactivation of pyrazolones with 1,6-enynes was investigated. The regioselectivity of the C–Hactivation/alkyne insertion is readily solved by using symmetric enyne coupling partners, and a C–H activation-triggered cascade reaction is realized, which involves alkyne insertion, tautomerization, and double cyclization to offer a class of structurally complex polycyclic architectures
