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
