Abstract

o-Tosylaminobenzaldehyde aminals react with propargyl alcohol and its phenyl ether on heating in acetonitrile in the presence of CuI to yield 3H-2-vinylidene-3-aminoindoline derivatives. Analogous reactions with phenylacetylene and dimethylethynylcarbinol result in 1,3-disubstituted propargylamines. The possibility of using the latter compounds in synthesis of quinoline derivatives was shown: cyclization of 1-(o-tosylaminophenyl)-1-morpholino-3-phenylprop-2-yne in the presence of H2SO4 and KOH gave 2-phenylquinoline and 2-phenyl-4-morpholinoquinoline, respectively. 3H-2-Phenoxymethylvinylidene-3-morpholinoindoline was studied by X-ray diffraction spectroscopy.
