“…These values are slightly higher than the spin value (1.73 B.M.) expected for one unpaired electron, indicating octahedral geometry around Cu(II) [34]. The magnetic moment value of the heterotrinuclear complex (III), which contains two Cu(II) ions, is 2.54 B.M.…”

New heteronuclear complexes containing oxorhenium(V), Cu(II), Ni(II), Fe(III), UO 2 (VI) and Th(IV) ions were prepared by the reaction of the complex ligand, [ReO(H 4 L)Cl]Cl 2 , where H 4 L ¼ 8, 17-dimethyl-6,15-dioxo-5,7,14,16-tetrahydrodibenzo[a,h][14]annulene-2,11-dicarboxylic acid, with the previous transition and actinide salts. Three heteronuclear Cu(II) complexes were isolated depending on the ratio of [ReO(H 4 L)Cl]Cl 2 : Cu(II) ion. When the ratios were 1 : 0.5, 1 : 1 and 1 : 2, the heteronuclear complexes {[ReO(H 3 L)Cl] 2 CuCl 2 (OH 2 ) 2 }SO 4 Á H 2 O (I), [ReO(H 3 L)Cl 2 Cu(OH 2 ) 2 (SO 4 )] (II) and {ReO(H 2 L)Cl[Cu(OH 2 ) 3 SO 4 ] 2 } (III) were obtained, respectively. Heteronuclear complexes of the other metal cations were obtained by mixing [ReO(H 4 L)Cl]Cl 2 with the metal salt in the ratio 1 : 1 to obtain the heteronuclear complexes [ReO(H 3 L)Cl 2 Ni(OH 2 ) 2 ](NO 3 ) 2 (IV), [ReO(H 3 L)Cl 3 Fe(OH 2 ) 3 ](NO 3 ) 2 (V), [ReO(H 3 L)ClUO 2 (NO 3 ) 2 (OH 2 )]Cl (VI) and [ReO(H 3 L)Cl 3 Th(NO 3 ) 2 (OH 2 )]NO 3 Á 2H 2 O (VII).The complex ligand coordinates with the heterometal ion via the carboxylate group, and the infrared bands as COO and s COO indicate that the carboxylate acts as a unidentate ligand to the heterometal cations. Cu(II) and Fe(III) cations in the heteronuclear complexes have octahedral geometry, while Ni(II) is square planar. Thermal studies explored the possibility of obtaining new heteronuclear complexes pyrolytically in the solid state from the corresponding mother complexes. The structures of the complexes were elucidated by conductance, IR and electronic spectra, magnetic moments, 1 H NMR and TG-DSC measurements as well as by mass spectroscopy.

“…Zentmayer and Wagner developed a convenient and fairly general procedure for preparation of acylanthranils or 3,1,4benzoxazinone (Zentmayer et al 1949). 2-Amidobenzoic acid on refluxing with acetic anhydride yield benzoxazinone, which reacts exothermally with ammonia and most amine in aqueous media to give high yield of quinazolin-4(3H)ones (Zhou et al 2004, Patel et al, 2002, Parmar et al, 1968. Reactions of substituted aromatic amine with acetanthranil have been extensively studied (Erred et al, 1976(Erred et al, , 1977a(Scheme 15).The synthetic methodology commence with the synthesis of anthranil amide by the oxidation of 2-amino benzonitrile, followed by its amidation using acid chloride and triethylamine to give the uncyclized amide intermediate, which on oxidative ring closure under basic conditions, using potassium hydroxide yield 2substituted-quinazolin-4(3H)ones (Roy et al, 2006, Witt et al, 2000, Bergman et al, 1990) (Scheme 16).…”

The main objectives of organic and medicinal chemistry are the design, synthesis and production of molecules having valuable human therapeutic effects. There are numerous biologically active molecules with six-membered rings, containing two heteroatoms. The development of research on biological activity of quinazoline compounds started with the synthesis of 2-methyl-3-phenylquinazolin-4(3H)-one that was later on approved to have has soporific and sedative action. This biological importance encouraged scientists to develop various new synthetic pathways of novel products. This review may cover and explain most of the old and recent synthetic methods of quinazolines and quinazolinones over more than a century.
