Abstract
AbstractA mild, sequential multicomponent reaction strategy for the regioselective synthesis of functionalized pentasubstituted pyrroles from readily accessible primary amines, 1,2‐diaza‐1,3‐dienes, and 2,3‐allenoates, has been developed. The process allows a [1N+2C+2C] annulation to be achieved through two sequential hydroamination reactions followed by an enamine‐carbocyclization. Moreover, allenoates, as synthetic equivalents of monoactived alkynes, permit the specific preparation of multifunctionalized pyrroles.
