RS)-Naphthotocopherol and its optically active short-chain analog were synthesized by the condensation of menadiol acetate with (3 RS,7 RS,11 RS)-isophytol and (3 RS,4 S)-3,4,8-trimethylnon-1-en-3-ol (ee ∼50%) in the presence of aluminosilicate Zeocar-10. Using (+)-camphor-10-sulfonic acid as a catalyst, naphthotocopherol analogs with the unsaturated isoprenoid side chain were obtained from (3 RS)-linalool or (3 RS
