11. The small amount of HBr generated from TMS-Br and water in solvents (not specially dried) is sufficient. All syntheses used RRR-tocopherols as starting materials. It was not tested whether the integrity of stereochemistry was maintained over the reaction steps.

21. The use of ICl or IBr had no effect on the outcome of the low-temperature route leading to 11.
22. Possible erosion of the stereochemistry, especially at C-2, as a consequence of the chemical manipulations was not further studied. However, comparison of the spiro-dimeric products with stereochemically pure (all-R)-compounds gave no indication of such a process.
