The reaction of 3-(2-cyanophenyl)quinazolin-4(3H)-one with various primary alkylamines gave 3-alkylquinazolin-4(3H)-ones via an addition of the nucleophile, ring opening, and ring closure (ANRORC) mechanism. This type of reaction required hydroxy group functionality in either the solvent or reagent. When hydroxylamine was used as nitrogen nucleophile, the intermediate of this reaction was isolated

Compounds that may selectively inhibit Oplophorus luciferase-derived bioluminescent complexes, e.g., NanoBiT® bioluminescent complex, are disclosed as well as compositions and kits comprising the compounds, and methods of using the compounds.
Some tetracyclic compounds containing the pyridodiazepine system condensed with the pyridofuro, pyridothieno and indole groups were synthesized. In the case of indole derivatives the outcome of the reaction is highly dependent by the nature of the substituents.
