✦ Synopsis


Total Synthesis of Natural α‐Tocopherol

(−)‐(S)‐2‐Methyl‐γ‐butyrolactone (2) represents a versatile chiral C~5~‐synthon. It serves as key intermediate in one of the syntheses of certain isoprenoid derivatives such as (R)‐dihydrocitronellol, (3__R__, 7__R__)‐hexahydrofarnesol and vitamin E of natural configurations. Their syntheses are described in detail.
