One-Pot Access to Boron-Doped Fused Heterocycles via Domino Cyclization of Bis-Diazidoboranes with Isonitrile

Boron-doped fused heterocycles have shown great potential in the field of functional materials. This study reports on the synthesis of a new class of bis-diazidoboranes and the discovery of their cycloaddition reaction with isonitriles. Triply fused boron-doped heterocyclic compounds were constructed in a one-pot process through a domino cycloaddition, providing an effective route for constructing complex boron-doped heterocyclic systems. The room temperature domino cyclization reaction of bis-diazidoboranes with isonitriles was reported for the first time. This one-step reaction leads to complex boron-doped fused heterocycles and provides a new strategy for the construction of boron-doped heterocyclic systems.image
