  Enantioselective synthesis of (+)-decipienin A

  摘要：

  The enantioselective synthesis of (+)-decipienin A has been carried out. The oxidation of 7-epi-cyperone 2 with molecular oxygen in the presence of methanolic KOH provides de C-6-hydroxylated derivative in quantitative yield. The oxidation of glycols 5a through a Swern oxidation and 14a with TEMPO radical opens up a route to the synthesis of 11-hydroxy sesquiterpenolides. All attempts of oxidation of 5a or 14a with other different oxidation reagents led invariably to fragmentation products. (C) 2001 Elsevier Science Ltd. All rights reserved.
