Studies on Tocopherol Derivatives. I. Conversion of β-, γ-, and δ-Tocopherol to α-Tocopherol

Chemical and Pharmaceutical Bulletin, 1971
A four-step methylation of β-, γ-, and δ-tocopherol to α-tocopherol is described. All of the intermediates are isolated and characterized. The purities of methylated tocopherols are determined by quantitative gas liquid chromatography. The four steps are Mannich reaction, acetolysis, reductive cleavage, and reduction.
