ABSTRACT:
3-Prenyl-substituted-2-alkyl menaquinones are made by reacting an alkali metal salt of a 3-alkyl-4-alkoxy or aralkoxy-1-naphthol with a prenyl halide, and oxidizing the resulting 2-prenyl-3-alkyl-4-alkoxy or aralkoxy-1-naphthol to the corresponding 3-prenyl-substituted-2-alkyl menaquinone. There is also disclosed a procedure for making the alkali metal salts involving the preparation of an ether-ester and hydrogenolysis.
