completion of reaction it was filtered through celite by washing with
ethylacetate and added water (50ml) extracted with same solvent
substituted quinolines. The present strategy offers the simple
route for the synthesis of 2ꢀsubstituted quinolines in excellent
yields. This methodology is also applicable for the synthesis of
3ꢀalkynylꢀ2ꢀarylꢀ2Hꢀindazoles. Further studies to extend the
scope of this methodology are underway.

(2x20ml). The combined organic layer washed with saturated NaOH
and brine solution and dried over anhydrous Na2SO4 and
concentrated under reduced pressure. The crude material was
purified by column chromatography on silica gel using petroleum
ether/ ethyl acetate (5ꢀ20%) to afford quinoline derivatives 4a-m in
62ꢀ89% yield. All the prepared compounds were characterized by
NMR and Mass spectroscopy techniques.

General Procedure for the preparation of 3-alkynyl-2-aryl-2H-
indazole (10a-f): A mixture of the aldehyde 1 (1.0 mmol) and
aniline 8 (1.2 mmol) was heated at 60°C for about 2h. Then RuCl3 (3
mol %), CuBr (30 mol%), alkyne 3 (1.2 mmol), and water (flashed
with nitrogen) (2ml) were added into the reaction mixture under
nitrogen. The mixture was stirred at rt for 10 min and then at 40°C
overnight. After the completion of the reaction it was extracted with
ethylacetate and then purified by column chromatography. Then the
pure Nꢀarylpropargylamine 9 was dissolved in 5 ml of ethanol and
added SnCl2.2H2O (4.0 mmol) then heated at 70°C for 2h. After the
completion of reaction it was concentrated to remove the solvent and
extracted.with ethylacetate. The organic layer washed with saturated
NaOH and brine solution and dried over anhydrous Na2SO4 and
concentrated under reduced pressure. The crude material was
purified by column chromatography on silica gel using petroleum
ether/ ethyl acetate (5ꢀ20%) to afford indazole derivatives 10a-f in
58ꢀ81% yield. All the prepared compounds were characterized by
NMR and Mass spectroscopy techniques

Conclusions
In summary we have reported first efficient example of oneꢀpot
reductive cyclization which yields to two different heterocycles
by varying the substrates. This technique has several
advantages such as ordinary reaction conditions, use of cheap
and stable starting materials, mild and efficient ecoꢀfriendly
catalyst. A broad range of alkynes, aldehyde and amines
participate in the reaction provide access to the large variety of
