Über die Chemie des Vitamins E. 5. Mitteilung. Die Synthese von rac. alltrans‐ζ1‐ und‐ϵ‐Tocopherol

Abstract
The synthesis of racemic all‐trans‐ζ1‐ (I) and ‐ϵ‐tocopherol (II) is described. Comparison with the corresponding natural specimens proved the all‐trans‐configuration of the side chain of ζ1‐and ϵ‐tocopherol isolated from wheat bran.
