“…Compared with other derivatives that exhibit high fluorescence, quinolone derivatives are among the best candidates in the design of electroluminescent materials [24,25]. Its fusion with other interesting heterocyclic nucleus such as pyrimidine have afforded systems with high usefulness, such the pyrimido [4,5-b]quinoline, which have been synthesized by diverse procedures, involving condensation and cyclocondensation reactions [26][27][28][29][30][31][32][33][34].…”

A series of 5-aryl-2-methylthio-5,12-dihydrobenzo[g]pyrimido [4,5-b]quinoline-4,6,11(3H) -trione was synthesized through an environmental friendly multicomponent methodology and characterized with FT-IR (Fourier Transform infrared spectroscopy), 1 H NMR (Nuclear Magnetic Resonance ), 13 C NMR and GC-MS (gas chromatography-mass spectrometry). The 5-(4-methoxyphenyl)-2-methylthio-5,12-dihydrobenzo[g]pyrimido [4,5-b]quinoline-4,6,11(3H)-trione 4c compound was characterized by X-ray single crystal diffraction. The geometry of 4c has been fully optimized using DFT (Density functional theory), B3LYP functional and 6-31G(d,p) basis set, thus establishing the ground state energy and thermodynamic features for the mentioned compound, which are in accordance with the experimental data and the crystal structure. The experimental results reveal a strong preference for the regioselective formation of 4c linear four fused rings over the angular four fused and suggest a possible kinetic control in product formation.

“…The quinoline and quinolinecarbaxdehyde derivates have been also used prevalently in organic light emitting diode researches due to their advance thermal and electrical properties [21,22]. They are transition metal catalyst [23] and used as ligand for metal cations [24]. They are also effective corrosion inhibitors [25].…”

Two new quinolines derivatives where crystallized from the acetylation reaction in low temperature ; between Baylis-Hillman products which had themselves been prepared from the Meth Cohn method and catalyzed by 1,4-diazabicyclo (Fatiha et al. in J Chem Crystallogr 42:989-996, 2012) octane and silicon dioxide or in pyridine and chloroform. Chemical structures have been established by spectral techniques of FTIR, 1H NMR and X-ray single crystal in low temperature. The crystal structure of (1a) crystallizes in triclinic space group P-1, a = 7.9145 (12) Å , b = 9.1412(11) Å , c = 10.7286(16) Å , a = 94.760(11)°, b = 105.988(13)°, c = 101.818(11)°, while (2a) crystallizes in orthorhombic non-centrosymmetric space group Pna21, a = 7.7237(12) Å , b = 20.2539(28) Å , c = 8.7164(12) Å , and its cohesion was found to be assured by O-HÁÁÁO and C-HÁÁÁO hydrogen bonds. Antimicrobial activity (in vitro) was evaluated by Gram-positive and Gram-negative bacteria. The compounds have shown good biological activity with Grampositive bacteria (Staphylococcus aurous and Staphylococcus coagulase-negative).Graphical Abstract Two new Quinoline derivatives have been prepared with good products yields; these products constitute original compounds, of great interest biological activity.
