Abstract:
A synthesis process for producing a conjugated fatty acid, comprising:(a) providing a fatty acid ester having somewhere in its carbon chain a chain of four carbon atoms such that carbon one bears one hydrogen and one hydroxyl group, carbon two bears two hydrogen atoms, and a double bond is positioned between carbon three and carbon four, and reacting with a chloride selected from the group consisting of toluenesulfonyl chloride, methanesulfonyl chloride, benzenesulfonyl chloride, alkylsulfonyl chloride, and arylsulfonyl chloride at a temperature in the range of 10-100Â° C. to form a sulfonyl ester; and (b) providing a conjugated fatty acid ester bearing said sulfonyl ester reacted with diazabicyclo-undecene, said conjugated fatty acid having a purity greater than 40%.
