enaminioesters from β-keto esters and primaryamines, activation of their allylic sp3 C–H, vinylic sp2 C–H and N–H bonds, multi C–C and C–N bond-forming cascade cyclization with 1,2-diketones and subsequent side-chain alkylation have been developed to construct functionalized pentasubstituted pyrroles and their chiral analogues. The scope of the domino reaction is successfully explored toward synthesis of highly
