The second approach involved the synthesis of a novel analogue of trazodone with a 4-phenylquinoline grouping replacing the chlorophenyl group of trazodone. The potential antidepressant activity of these new compounds has been demonstrated by their antagonism to the reserpine-induced hypothermia in mice. Both length of the side chain and isosteric displacements within the side chain affect the value of

that the base-catalyzed thio-lactamization of 2-(1-arylvinyl)anilines with CS2 is a powerful methodology to synthesize quinoline-2-thiones. This thio-lactamization uses inexpensive and versatile 2-(1-arylvinyl)anilines, which are easily available from the reaction of amines and alkynes. Compared to the known strategy in the literature, this method features the advantages like a short synthesis step and

iodine-induced sulfonylation of quinoline-2-thiones with sodium arenesulfinates as sulfur sources for the synthesis of 4-aryl-2-(arylsulfonyl)quinoline derivatives is described. The 4-aryl-2-(arylsulfonyl)quinoline derivatives can be obtained in a moderate to good yields. This C–S bond cleavage and C–Scross-coupling proceeds in the absence of a metal under inexpensive and nontoxic conditions and it displays a

Here, we report a base-controlled chemo-selective reaction of vinylanilines with alkyl/aryl isothiocyanates to afford quinolino-2-thione and 2-aminoquinoline derivatives. The quinolino-2-thiones could be obtained in high yields in the presence of Et3N. Particularly interesting is that the reaction could produce the 2-aminoquinolines in the presence of K3PO4 with high selectivity.
在这里,我们报告乙烯基苯胺与烷基/芳基异硫氰酸酯的碱控制化学选择性反应,以提供喹啉基-2-硫酮和2-氨基喹啉衍生物。在Et 3 N存在下,可以高产率获得喹啉-2--2-硫酮。特别有趣的是,在K 3 PO 4存在下,该反应可以产生2-氨基喹啉,具有高选择性。
One-Pot Synthesis of Quinoline-2(1H)-thiones from 2-Isocyanostyrenes via Electrocyclic Reaction of the Corresponding 2-Isothiocyanatestyrenes
The reaction of α-substituted 2-isocyanostyrenes, which could be readily prepared from commercially available 2-aminophenyl ketones or 2-aminobenzonitriles, with sulfur in the presence of a catalytic amount of selenium proceeded smoothly to give the corresponding 2-isothiocyanatestyrenes. The latter spontaneously underwent the electrocyclic reaction to afford 4-substituted quinoline-2(1H)-thiones in one-pot with isolated yields ranging from 37 to 91%.
