Iron-catalyzed aryl C–H and vinyl C–H bonds activation to give valuable substituted indole products was reported. The reaction shows high functional group tolerance.
A facile and efficient method for the synthesis of substituted pyrroles from enaminoesters and nitroolefins is reported. This general procedure provides a wide variety of multisubstituted pyrroles in good to excellent yields under mild reaction conditions.
novel palladium-catalyzed regioselective oxidative carbonylation of tri-substituted alkenes with CO and alcohols for the synthesis of α,β-unsaturated esters has been developed. Experimental studies and DFT calculations suggested that the reaction proceeded through alkoxylation of the palladium(II) catalyst, CO and CC double bond migratory insertion, β-(N)H elimination and tautomerization cascade steps
A novel and efficient copper-catalyzed tandem oxidative cyclization/1,2-amino migration of readily available enamino esters for the synthesis of substituted pyrroles has been developed. In this reaction, one C–N bond was cleaved, and two new C–N bonds and one C(sp2)–C(sp2) bond were constructed in one pot. This catalytic system has the obvious advantages of mild reaction conditions and the use of oxygen
