Source of material
To a three necked round-bottom flask equipped with a stirrer bar, condenser and rubber septa was added in sequence 6-bromo-8-iodo-4-oxo-1,4-dihydroquinoline-3-carbaldehyde (0.50 g, 1.32 mmol), PdCl2(PPh3)2 (0.04 g, 0.66 mmol), CuI (0.02 g, 0.13 mmol), Cs2CO3 (0.51 g, 1.58 mmol) and dioxane (20 mL). The mixture was purged with nitrogen gas for 20 minutes and a balloon filled with nitrogen gas was connected to the top of the condenser. Phenylacetylene (0.20 g, 1.98 mmol) was added via syringe and the mixture was heated at 80 °C under inert atmosphere for 6 h. The mixture was quenched with an ice-cold water and the product was extracted with chloroform. The combined organic solutions were washed with brine and dried over anhydrous MgSO4. The salt was filtered off and the solvent was evaporated under reduced pressure. The residue was purified by column chromatography on silica gel using toluene as an eluent and then recrystallized from chloroform to afford 8-bromo-6-oxo-2-phenyl-6H-pyrrolo[3,2,1-ij]quinoline-5-carbaldehyde as a solid (0.25 g, 58%); m.p. 224–225 °C; IR: νmax (ATR) 545, 769, 876, 933, 1067, 1170, 1295, 1353, 1488, 1590, 1638, 1683 cm−1; 1H-MNR: δH (500 MHz, CDCl3) 7.20 (1H, s, = CH), 7.62 (1H, t, J = 8.5 Hz), 7.66 (2H, d, J = 9.0 Hz), 7.76 (2H, d, J = 8.5 Hz, Ar), 8.07 (1H, J = 1.5 Hz, H-5), 8.29 (1H, d, J 1.5 Hz, H-7), 8.57 (1H, s, CHO) 10.1 (1H, s, NH); 13C-NMR: δC (125 MHz, CDCl3) 111.0, 114.3, 119.8, 121.2, 124.1, 124.9, 127.8, 128.0, 129.8, 130.6, 132.1, 134.7, 139.9, 142.8, 176.9, 189.3; HRMS (ES): found 352.9874. C18H11NO279Br requires 352.9874.
Experimental details
Intensity data was determined on a Bruker Venture D8 Photon CMOS diffractometer with graphite-monochromated MoKα1 (λ 0.71073 Å) radiation at 173 K using an Oxford Cryostream 600 cooler. Data reduction was carried out using the program SAINT+, version 6.02 [1] and face-indexed [1] absorption corrections were made using the program XPREP [1]. Space group assignments was made using XPREP [1]. The structure was solved in the WinGX [2] Suite of programs, using direct methods through using SHELXS [3] and refined using full-matrix least-squares/difference Fourier techniques on F2 using SHELXL [3]. All hydrogen atoms were placed at idealized positions and refined as riding atoms with isotropic parameters 1.2 times those of their parent atoms. Diagrams and publication material were generated using ORTEP-3 [2], and PLATON [4].
Discussion
Multisubstituted pyrrolo[3,2,1-ij]quinolines exhibit wide range of biological properties including analgesic, anti-pyretic, anti-inflammatory, antiviral, anticonvulsant and antimitotic properties and some derivatives have also found application in agriculture as antibacterial and antifungal agents against the diseases of rice plants [5], [6], [7], [8], [9], [10]. Non-conventional approach towards these compounds involve the use of transition metal catalysed tandem Sonogashira cross-coupling of 8-halogenated quinolin-4-one or quinoline scaffold with terminal acetylene and subsequent cycloisomerization of the intermediate 8-alkynylated derivative to append a five membered ring [11], [12], [13], [14], [15], [16]. Chloromethyleneiminium salt commonly known as the Vilsmeier-Haack (V—H) reagent has been employed extensively in the formylation, cyclization and ring annulation reactions [16]. The Vilsmeier reaction of 2-aminoacetophenone has previously been shown to afford 4-chloroquinoline-3-carbaldehyde, which upon acid-mediated hydrolysis afforded the 4-oxoquinoline-3-carbaldehyde derivatives [17]. This reagent has also been used before to convert 8-methyl-2-phenyl-4H-pyrrolo[3,2,1-ij]quinolin-6(5H)-one into 6-chloro-8-methyl-2-phenyl-4H-pyrrolo[3,2,1-ij]quinoline-1,5-dicarbaldehyde [13]. In this investigation, 2-amino-5-bromo-3-iodoacetophenone was subjected to the Vilsmeier-Haack reaction followed by acid-mediated hydrolysis of the intermediate 6-bromo-4-chloro-8-iodoquinoline-3-carbaldehyde to afford 5-bromo-4-chloro-8-iodo-4-oxoquinoline-3-carbaldehyde. This mixed dihalogenated quinolinone derivative was found to undergo Sonogashira cross-coupling via Csp2–I substitution to afford 8-bromo-6-oxo-2-phenyl-6H-pyrrolo[3,2,1-ij]quinoline-5-carbaldehyde.
Single crystals of the title compound suitable for X-ray analysis were obtained by slow evaporation of chloroform and the structure of the compound was distinctly confirmed by single crystal X-ray diffraction (XRD) analysis. 8-Bromo-6-oxo-2-phenyl-6H-pyrrolo[3,2,1-ij]quinoline-5-carbaldehyde crystallizes in the Pbcn space group, and the asymmetric unit contains one molecule of the compound. The crystal structure reveals that the pyrroloquinolinone moiety is planar with the 2-aryl group twisted out of plane [torsion angles: N(1)—C(11)—C(12)—C(17) = 48.7(4)° or C(10)—C(11)—C(12)—C(13) = 47.3(5)°]. Oxygen atom of the 5-carbaldehyde group is in anti-orientation relative to the 6-oxo atom presumably to avoid electronic repulsion. The molecules are aligned in parallel planes and are held together by several intermolecular C—H⋯O and C—H⋯Br bond interactions and further stabilized by π⋯π stacking.
