Cu (I)-catalyzed synthesis of polysubstituted pyrroles from dialkyl ethylenedicarboxylates and beta-enamino ketones or esters in the presence of O2.
A straightforward method for the synthesis of polysubstituted pyrroles was achieved easily from oxidative cyclization of beta-enamino ketones or esters and alkynoates catalyzed by CuI in the presence of O(2).
