Functionalized N-containing heterocyclic scaffolds derived from N-substituted pyrroles via inter- and intramolecular annulations

Add time:08/10/2019    Source:sciencedirect.com

Two series of N-containing heterocycles were synthesized by one-step intramolecular or intermolecular annulations of N-substituted pyrrole-2-carbaldehydes and pyrrole-2-carbonitriles. These facile and atom-economic synthetic routes involved the inherent three potential electrophilic and nucleophilic reactive sites of the synthons and the reaction solvent plays a crucial role leading to these different types of products. Additionally, plausible mechanisms are proposed.
