Abstract

The ^13^C NMR spectra of methyl 2‐pyrone‐3‐, 4‐, 5‐ and 6‐carboxylates were studied and the substituent effects on the 2‐pyrone ring were compared with those of some model compounds. ^1^H NMR spectra were also recorded and discussed. The long range ^13^C, ^1^H coupling constants were obtained, discussed and proved useful in signal assignments.

## Abstract Carbon‐13 n.m.r. spectra have been obtained for some methyl and phenyl substituted 2__H__‐azirines. The higher field resonance of C‐2 than that of the corresponding aziridine carbon is interpreted in terms of ring strain. Substituent effects on the chemical shifts of the azirine ring ca

REFERENCE DATA causes the electron density to be comparatively lower at C-3 and C-5 than at C-2 and C-4, so that the former signals resonate at lower fields. Distinction between the signals of the C-2/C-4 and C-3/C-5 pairs was achieved by comparing the C-H coupling patterns of 5 and 1. Compounds 1,
