| Abstract: | By treating 1-alkylindolines with 1-benzoylpyrylium salts in the presence of Lewis acids, good yields of 1-alkyl-5-(pyrid-4 -yl) indolines can be obtained. 1-alkyl-5-benzoylindolines are side products. The structures of the reaction products were demonstrated by UV and IR spectra, thin-layer chromatography, and dehydrogenation to the corresponding pyridylindoles.For the previous paper see [1]. |
