摘要：

H-1, C-13 and N-15 NMR data are presented for seven indolizine derivatives in solutions of dimethyl sulphoxide and trifluoroacetic acid (TFA). The TFA solutions contain species protonated at position N-1 in all cases. The most definitive evidence for the site of protonation is provided by the N-15 results.
