The stereochemical assignments were based on the known greater coupling constants (9–10 Hz) for cis vicinal cyclopropyl hydrogens than for the trans isomer (6–7 Hz) and the greater chemical shift difference for the geminal CH3's of the trans isomer. Our values were in agreement with those reported by
