A green and operationally simple approach for the diverse synthesis of fused quinoxalines and benzimidazoles from o-alkynylaldehydes and amines having an N-tethered nucleophile using Ag(I) as the catalyst in water, is described. The X-ray crystallographic studies confirmed the proposed mechanistic pathway and the cyclized product.
