Abstract :
(±)-Untenone A, one of the marine cyclopentanoids, has been conveniently synthesized via (±)-cis-1-hexadecylcyclopent-2-en-1,4-diol 9 which has been produced from 1-hexadecylcyclopenta-1,3-diene 6 via photo-oxidation and the following reduction. The key step of the present synthesis is the selective alkylation of cyclopenta-1,3-diene to form 6. Optically active (−)- and (+)-untenone A have been prepared from (−)- and (+)-9, respectively, after enzymatic kinetic resolution of (±)-9.
