The reaction of quinolines with CF3-ynones resulted in the formation of 1,3-oxazinoquinolines. Subsequent treatment of the reaction mixture with a base initiated deep structural transformation of primary products. Both steps proceed in very high yield. As a result, unusual rearrangement of 1,3-oxazinoquinolines to form either 2-arylquinolines or 2-aryl-3-trifluoroacetylquinolines was discovered. The decisive role of the base in the reaction direction was shown. Using these reactions, highly efficient pathways to 2-arylquinolines and 2-aryl-3-trifluoroacetylquinolines were elaborated to provide the corresponding compounds in high yields using a simple one-pot procedure. The possible mechanism of rearrangement is discussed.

Based on thermogravimetric characteristics first obtained for the model 6H-indenoquinoline, the scheme of thermal conversions of this compound in the temperature range 20-700 deg C has been proposed, and the limit of its thermal stability (ca. 300 deg C) has been determined.This temperature is recommended as the optimum for synthesizing fused benzoaza(diaza)fluorenes.Based on the results of X-ray structural analysis, the molecules of the studied indenoquinoline form centrosymmetric pairs, which are arranged in (110) layers.The molecules are orientationally disordered self-association of these molecules is similar to the ?-? association of fused heterocyclic systems with ?-excessive and ?-deficient fragments.It has been suggested that interferon-inducing and antitumor compounds with an annelated indenyl fragment have a common mechanism of action according to the intercalation model of stacking structures. - Key words: CH-acids; 6H-indenoquinoline, heterogeneous catalytic dehydrogenation, thermogravimetric and X-ray structural analysis; interferon-inducing and antitumor intercalators; topological factor; stacking structures.
