Abstract

The proton spectra of bicyclo[3.2.0]hept‐2‐en‐6‐one and the 7,7‐dimethyl, 7,7‐dichloro and 7‐endo‐chloro derivatives were analysed and the chemical shifts and coupling constants are reported. Molecular modelling and chemical shift calculations together with the observed couplings show that only minor conformational changes occur on substitution. Copyright © 2001 John Wiley & Sons, Ltd.
