(+/-)-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. (C) 2010 Elsevier Ltd. All rights reserved.
(+/-)-Untenone A 是一种海洋环戊烷类化合物,已通过 (+/-)-顺式-1-十六烷基环戊-2-烯-1,4-二醇 9 方便地合成,而 9 则由 1-十六烷基环戊烯-1,3-二烯 6 经过光氧化和随后的还原反应制得。本合成的关键步骤是环戊烯-1,3-二烯的有选择性烷基化,以形成化合物 6。光学活性 (-)- 和 (+)-Untenone A 分别由 (-)- 和 (+)-9 制备,前提是 (+/-)-9 经过酶促动力学拆分。© 2010 Elsevier Ltd. 保留所有权利。
