A convenient one-potsynthesis of 2,3-disubstituted, 2,3,6-trisubstituted, and 2,3,6,7-tetrasubstituted quinoline analoguesfrom terminal alkynes via sequential ruthenium(II) and para-toluenesulfonic acid (p-TSA) co-catalyzed reactions is described. The catalytic process is shown to take place first via intermediate formation of an allyl ketone and then addition of an aniline derivative to the allyl

one-pot synthesis of polysubstitutedquinoline derivatives has been demonstrated by using sulfamic acid as a reusablecatalystundersolvent-freeconditions. The synthetic method provides the basis and advantages of a simple experimental procedure and easy recovery and reuse of catalyst, which makes it a highly practical and environmentally benign pathway for the synthesis of polysubstituted quinolines
