Abstract
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. [ABSTRACT FROM AUTHOR]
