  First synthesis of decaturin C, an antiinsectant diterpenoid isolated from Penicillium thiersii

  摘要：

  The first synthesis of (+)-decaturin C, an antiinsectant diterpenoid isolated from Penicillium thiersii, was accomplished by starting from (R)-(-)-Wieland-Miescher ketone, in which our original spiro-cyclization reaction was featured as a key step. (C) 2012 Elsevier Ltd. All rights reserved.
