investigated. By regulating the substituent electronic effect and solvent effect, ring-chain tautomerization equilibrium was readily regulated in solution. The adjacent amide NH participates in intramolecular hydrogen bonding, as revealed by crystal analysis. Furthermore, the addition of acid and the change of solvent allowed turning on/off the intramolecular cyclization from the amide group to create fused
