- The alcohols 3a were separated by column chromatography into endo- and exo-3a. The stereochemistry was assigned on the basis of the fact that sodium borohydride reduction of 4a gave exclusively the endo-3a.
- The alcohols 8 were separated by chromatography into endo- and exo-8. The stereochemical assignment was based on the fact that sodium borohydride reduction of 9 gave exclusively the endo-8.
