A series of stable N-acyl benzoazetinones have been synthesized in moderate to good yields (58–85%) from easily available substrates such as 2-(N-acyl) amino benzoic acids through intramolecular amidation under mild conditions. These geometry-optimized benzoazetinones were docked in the model target of P450, class CYP53A15, a benzoate 4-monooxygenase abundantly found in the genome of ascomycetes and Basidiomycetes classes of pathogenic fungi. Low per residue root-mean-square deviation (RMSD) of modeled structure of the enzyme indicated similar topology as template (4D6Z.pdb). Observed score judges site-specific docking, and the interaction of quantum mechanically optimized benzoazetinone derivatives with the target enzyme. These results suggest that 3i is the best antifungal agent. The specific hydrophobic substituent in the benzoazetinones contributed to the stability of ligand–target complex. Overall, the study provided insight into the specificity of the site-specific interactions, thereby, facilitating the possibility of development of broad-spectrum antifungal agents against opportunistic and infectious fungi.

Solid hydrolysis of 2-substituted 3,1-benzoxazin-4-ones are presented.O18 experiments with labelled water and hydrolysis in acidic comditions show the reaction occurs on >C=N- function.A protonated intermediate for the reaction is proposed.Theoretical calculations are in agreement with the assumed intermediate.
