A Synthesis of (Z)-Octadec-9-enedioic Acid
Australian Journal of Chemistry
48(11) 1893 - 1897
The monomethyl ester of azelaic acid was transformed into two fragments, namely [8-( methoxy -carbonyl) octyl ] triphenylphosphonium bromide and methyl 9-oxononanoate. A Wittig reaction between these two fragments produced dimethyl (Z)-octadec-9-enedioate and subsequent hydrolysis gave the title diacid. Interestingly, the same diacid was available directly from oleic acid in a published procedure which utilized a mutant strain of Candida tropicalis.
