The synthesis of novel pyrrolo[1,2‐a]azolo‐(azino‐)[c]quinazolines by tandem reaction of 2‐(azolyl‐(azinyl‐))anilines with oxocarboxylic acids was described in this article. The mechanism of obtained compounds formation was proposed, and the intermediate of the heterocyclization has been isolated and characterized. The IR‐, 1H and 13C NMR‐, chromato‐mass spectra of synthesized compounds were studied

5+1-Heterocyclization as preparative approach for carboxy-containing triazolo[1,5-c]quinazolines with anti-inflammatory activity
zoic acid () has been identified as compound with most expressed anti-inflammatory activity and significant effect on the levels of marker of inflammatory processes. Moleculardocking study towards СОХ-1 and СОХ-2 has been conducted to substantiate possible mechanism of obtained compounds anti-inflammatory activity. It has been found that fixation of 4-(2-(ethoxycarbonyl)-5,6-dihydro-[1,2,4]triazolo[1
