Preparation

Synthesis of 2-phenylquinoline: Quinoline (1.0 g, 7.742 mmol) and phenyl lithium (2.30 mL, 2 M, 23.22 mmol) were reacted according to general procedure. Purification of the residue by silica gel column chromatography (EtOAc:MeOH:Et3N; 10-30:1:1 or PhMe:MeOH:Et3N; 10:1:1) gave 2-phenylquinoline (0.66 g, 42%) as an orange solid.Aniline (0.140 g, 1.50 mmol) and cinnamaldehyde (0.132 g, 1.00 mmol) were dissolved in toluene in a reaction vial equipped with a magnetic stirrer bar, followed by the addition of K10 (0.50 g). The reaction mixture was heated at a temperature of 110 ?C for 3 hours. After completion of the reaction, the crude product was purified by column chromatography over silica gel eluting with a mixture of Hexane : Ethyl acetate (20:1) to produce 2-Phenylquinoline as a yellow solid (0.044 g, 21%); (m.p. 82-84 ?C) (lit. 84-85 °C); Rf 0.67 (20:1 hexane:ethyl acetate);1H NMR (400 MHz, CDCl3) δH 7.46-7.51 (1H, m, H-4’), 7.53-7.56 (3H, m, H-6, 3’, 5’), 7.73- 7.77 (1H, m, H-7), 7.85 (1H, d, J = 8.31 Hz, H-5), 7.88-7.91 (1H, d, J = 8.31 Hz, H-3), 8.18- 8.27 (4H, m, H-4, 8, 2’, 6’)13C NMR(400 MHz, CDCl3) δC 119.2 (C-3), 126.7 (C-6), 127.2 (C-4a), 127.5 (C-2’, 6’), 127.9 (C-5), 128.4 (C-3’, 5’), 128.7 (C-4’), 128.9 (C-7, 8), 129.8 (C-4), 130.3 (C-1’), 137.9 (C-8a), 157.2 (C-2)

Substrate-Tuned Domino Annulation for Selective Synthesis of Poly-substituted Benzo[ f]imidazo[2,1- a][2,7]naphthyridines and 3-Azaheterocyclic Substituted 2-Arylquinolines

A domino annulation/oxidation of heterocyclic ketene aminals (HKAs) and 2-aminochalcones has been developed for the selective synthesis of poly-substituted benzo[f]imidazo[2,1-a][2,7]naphthyridines and 3-azaheterocyclic substituted 2-arylquinolines. These reactions proceed well under mild conditions without any additives. Plausible mechanisms for such a polycyclic ring system assembly were also proposed. Moreover, benzo[f]imidazo[2,1-a][2,7]naphthyridine 3g displayed a fluorescence effect, demonstrating the potential applications in organic optical materials.

A Domino Heck Coupling-Cyclization-Dehydrogenative Strategy for the One-Pot Synthesis of Quinolines

An efficient, one-pot, domino synthesis of quinolines via the coupling of iodoanilines with allylic alcohols facilitated by palladium catalysis is described. The overall synthetic process involves an intermolecular Heck coupling between 2-iodoanilines and allylic alcohols, intramolecular condensation of in situ generated ketones with an internal amine functional group, and a dehydrogenation sequence. Notably, this protocol occurs in water as a green solvent. Significantly, the method exhibits broad substrate scope and is applied for the synthesis of deuterated quinolines through a deuterium-exchange process.
