✦ Synopsis

Abstract

The ^13^C NMR spectra of all azabenzenoid isoxazolopyridines and some of their chloro derivatives are discussed. All ^13^C resonances were unambiguously assigned by means of gated decoupled spectra, from which one‐bond and long‐range ^13^C^1^H coupling constants have been determined from line splittings.

## Abstract The carbon‐13 NMR spectra of a series of __exo__‐and __endo__‐epimers of 2‐substituted benzonorbornene (2‐substituent = OH, OCHO, Br, NH~2~, NHMe or NMe~2~) have been examined. The spectra are readily assigned by comparison with the coupled and off‐resonance proton decoupled spectra as
