Epoxydes cyclopentaniques conformationnellement homogènes. II—Détermination des configurations au moyen des déplacements chimiques induits par compléxation a l'Europium

The configuration of conformationally homogeneous epoxides in trans bicyclo-(n.3.0) alkanes is established by progressive complexation with Eu(dpm)₃. The examples described demonstrate the importance of this method which is superior to all the other physicochemical methods already used to determine the cyclopentane epoxide configuration.
