Abstract
The proton magnetic resonance spectra of
indolizine, indolizine-1,3-d2, 1- and 2-methylindolizine, 2,3-,
2,5-, 2,6-, and 2,7-dimethylindolizine and 1-, 2-, and 3-azaindolizine have
been determined at 100 and/or 60 Mc/s. Unequivocal assignments have been made
to all protons and the coupling constants and chemical shifts for indolizine
and its aza analogues have been obtained by an iterative procedure. Long-range
coupling constants involving protons separated by five and six bonds have been
observed.
