Anacardic acid was isolated from CNSL, dimethoxylated into (E)-methyl 2-methoxy-6-(pentadec-8-enyl)benzoate which was subsequently hydrogenated into methyl 2-methoxy-6-pentadecylbenzoate. Benzylic bromination of the methoxyester, and dehydrobromination afforded (E)-methyl 2-methoxy-6-(pentadec-1-enyl)benzoate which upon ozonolysis gave methyl 2-formyl-6-methoxybenzoate. Oxidation and dehydration of <strong>8</strong> formed methoxyphthalic anhydride (<strong>10</strong>). The work reported in this paper has further demonstrated the resourcefulness of cashew nut shell liquid as a renewable natural resource for synthesis of fine and industrial chemicals</em></p> <div><em><span lang="EN-US">Anacardium occidentale</span></em></div> <div><span lang="EN-US">, Cashew Nut Shell Liquid, Anacardic acid, 2-formyl-6-methoxybenzoate, methoxyphthalic anhydride</span></div> <p> </p>}, number={1}, journal={Tanzania Journal of Science}, author={Kisula, Lydia and Mdachi, Stephen J.M. and Koning, Charles de and Mgani, Quintino A.}, year={2021}, month={Apr.}, pages={27–37} }
