  Synthesis of longithorone B, a sixteen-membered farnesylated p-benzoquinone

  摘要：

  The intramolecular coupling reactions at the C-1position of the 10Z-farnesyl moiety appended at the 2'-position of 4'-methoxy phenol derivatives were examined with the aid of Hf(OTf)(4)and LiClO4. When the phenol was protected with a TBDMS group, meta coupling predominated while para coupling occurred efficiently when protected with a pivaloyl group. The para-coupled product was transformed to longithorone B, recently isolated from a tunicate. (C) 1999 Elsevier Science Ltd. All rights reserved.
