exhibits a broad substrate scope and excellent functional group tolerance, and affords a series of biologically important 1,3‐benzoxazine derivatives in good to excellent yields. Moreover, the successful late‐stage functionalization of pharmaceutically relevant compounds further renders the approach valuable.

An efficient and metal-free approach to the construction of diverse functionalized furan derivatives has been developed from ene-yne-ketones and 1,3,5-triazinanes. As an atom-economical and environment-friendly protocol, the new conditions are suitable for selective C–N and C–O bond formation of a wide range of polysubstituted furans in one pot.
