Аннотация: A series of 4,5-diphenyl-7H-thieno[2′,3′:3,4]pyrido[2,1-b]quinazolin-7-ones was synthesized via the Rh(III)-catalyzed annulation of 2-thienylquinazolin-4(3H)-ones with diphenylacetylene. 2-Phenylquinazolin-4(3H)-one amide alcoholysis and double C–H functionalization proceeded under the same reaction conditions with the formation of 2,3,7,8-tetraphenyl-1H-benzo[d,e][1,8]-naphthyridine derivatives. All compounds possess fluorescence properties in MeCN and toluene solutions as well as in the solid state. The aggregation induced emission (AIE) properties and the ability to detect Fe3+ cations were evaluated.

N,O-BIDENTATE LIGANDS -- BPh2 COMPLEXES -- BF2 COMPLEXES
Аннотация: Novel N,O-bidentate BF2 and BPh2 complexes have been prepared in good to excellent yields through coordination of 8-hydroxy-2-methylquinolines and 2-(2-hydroxyphenyl)-3H-quinazolin-4-ones with boron trifluoride etherate or triphenylborane under mild conditions. All complexes have been characterized by H-1, B-11 and F-19 NMR, mass-spectrometry and X-ray crystallography data. Some complexes have been found to exhibit a significant fluore.scence in acetonitrile solutions. Electronic and site effects of substituents in both heterocyclic and phenol fragments proved to have a profound impact on quantum yields.

(E)-2-STYRYLQUINAZOLIN-4(3H)-ONES -- LUMINESCENCE -- ORTHO-HYDROXYSTYRYLQUINAZOLINONES
Аннотация: Photoinduced transformations of 2-styrylquinazolinones in solutions were studied using absorption and NMR spectroscopy methods. A possibility of control of the photochemical isomerization rate of quinazolinone 2-(hydroxyaryl)ethenyl derivatives by changing the pH of the medium was demonstrated. The bases and the solvent nature also affect the luminescence intensity of solutions of these compounds in the wavelength range of 550-650 nm. The differences in the steric organization of the ortho-hydroxystyryldiazinone system in crystals and in solutions related to the turn of the aryl group were found. Their influence on the competing processes of luminescence and photochemical transformation of the ethylene fragment were shown. The fact of reversible photo/thermal E-Z-isomerization was established for (E)-2-(2-hydroxystyryl)-3-phenylquinazolin-4(3H)-one.

Аннотация: 5-Fluoroquinazoline-2,4-diones and their 2-thio analogs were obtained from 6-fluoroanthranilic acid. Two convenient routes to 5-fluoroquinazolin-4-ones involved cyclocondensation of 6-fluoroanthranilamide with acid chlorides (anhydrides) or with aromatic (heterocyclic) aldehydes. A method for the synthesis of 7-fluoroquinazolin-4-one from 2,4-difluorobenzoic acid was proposed
