Title: Synthesis of indoles from pyridinium salts

Journal Article · · Chem. Heterocycl. Compd. (Engl. Transl.); (United States)
DOI:https://doi.org/10.1007/BF00546736· OSTI ID:7004926

The detailed analysis of the products of the interaction of nitropyridinium salts with ketones and alkylamines resulted in new data testifying in favor of the previously proposed scheme for the formation of indoles from pyridinium salts. The PMR spectra were taken on a Bruker WM-500 spectrometer for the compounds (IXa,b) in CDCl/sub 3/, and (IVg, i-Z) in acetone-D/sub 6/, and a Varian T-60 spectrometer for the alkylindoles (IVa,c,h) in CDCl/sub 3/, with reference to HMDS. The /sup 13/C NMR spectra were taken on a Bruker WM-250 spectrometer in CDCl/sub 3/. The mass spectra were taken on a Finnigan-4021 instrument.
