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

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。

K2CO3-catalyzed thio-Michael addition using quinoline-2-thiones and α,β-unsaturatedcarbonylcompounds was used to assess the chemoselective construction of C–S and S–S bonds under mild reaction conditions in different solvents. The C–S bond showed a better chemoselective construction in EtOH whereas the S–S bond showed a better chemoselective construction in 1,4-dioxane. The corresponding products, generated
