Abstract
A novel four-component strategy for the selective synthesis of fused azepino[5,4,3-cd]indoles and pyrazolo [3,4-b]pyridines has been established. The bond-forming efficiency, accessibility of starting materials and substrate scope provide invaluable access to tetra-, and bis-heterocyclic scaffolds.
