Abstract
Atropoisomerism, a type of isomerism associated with restricted rotational properties about certain bonds, is present in endo-cis-N-(o-tolyl)bicyclo[2 .2.1]heptene-2,3-dicarboximide and its oxidation products, the correspondin g diol and diacid. These three compounds were studied by variable-temperatu re NMR and molecular modelling. Small differences in carbon and proton chem ical shifts can be attributed to slight changes in geometry due to interact ions of rotating groups. Copyright (C) 1999 John Wiley & Sons, Ltd.
