Abstract

NEW MATERIAL:5,8,11,14,17-Eicosapentaenoic acid α-tocopherol ester.
USE: Blood platelet coagulation inhibitor: it is more stable and absorbable than 5,8, 11,14,17-eicosapentaenoic acid.
PREPARATION: 5,8,11,14,17-Eicosapentaenoic acid or its reactive derivative such as its acid halide or acid anhydride and α-tocopherol are made to react in an inert solvent such as water or dichloromethane at room temperature to refluxing one of the solvent for 1W20hr to give 5,8,11,14,17-eicosapentaenoic acid α-tocopherol ester. When 5,8,11,14,17-eicosapentaenoic acid is used directly, the reaction preferably is effected in the presence of N,N-dicyclohexylcarbodiimide or 2-substituted pyridinium salt and a base.
