资源简介:
We report herein a new strategy of the Rh­(III)-catalyzed C–H activation/cyclization of indoles and pyrroles, for the divergent synthesis of privileged heterocycles. A simple derivation of indoles and pyrroles to N-carboxamides with oxidative bidentate directing group could enable rhodacycle formation and late-stage redox-neutral cyclization with alkynes, alkenes and diazo compounds, for access to five- and six-membered fused heterocycles, such as pyrimido­[1,6-a]­indol-1­(2H)-one, 3,4-dihydropyrimido­[1,6-a]­indol-1­(2H)-one, and 1H-imidazo­[1,5-a]­indol-3­(2H)-ones. Kinetic isotope effect study was conducted, and a plausible mechanism was proposed. Furthermore, this protocol was applied to concise synthesis of 5-HT3 receptor antagonist in gram-scale.
