Stavytskyi, Viktor published the artcileTandem heterocyclization of 2-(azolyl-(azinyl-))anilines as an efficient method for preparation of substituted pyrrolo[1,2-a]azolo-(azino-)[c]quinazolines, Formula: C10H10O3, the publication is Journal of Heterocyclic Chemistry (2020), 57(3), 1249-1260, database is CAplus.
The synthesis of novel pyrrolo[1,2-a]azolo(azino)[c]quinazolines I (R1 = Me, Ph, HO2C, HO2CCH2CH2; R2 = Me, Ph, 4-i-PrC6H4, 2-thienyl) and II (R1 as above; X = N, CHMe, CHPh, etc.) by tandem reaction of the corresponding o-aminophenyl-substituted azines and azoles with oxocarboxylic acids R1C(O)CH2CH2CO2H is described. The mechanism of formation of the compounds I and II 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 for estimation of their structure and spectral patterns features. The mol. structure of the obtained compounds was addnl. proved by X-ray diffraction method.
