The cycloalkeno[1,2-d]furo[2,3-b]pyridine skeleton was conveniently synthesized from fused 4-(2-cyanovinyloxy)butanenitriles in one step through sequential intramolecular Michael addition, β-elimination and intramolecular nucleophilic addition. This sequence thus consists of a novel Truce-Smiles type rearrangement followed by cyclization. The 5-amino derivatives were transformed further to lactams in good yields.
