  描述：

  ethyl (2E,6E)-10-chloro-3,7,11-trimethyldodeca-2,6,11-trienoate 在 咪唑 、 4-二甲氨基吡啶 、 aluminum oxide 、 18-冠醚-6 、 二异丁基氢化铝 作用下， 以 N,N-二甲基甲酰胺 、 xylene 为溶剂， 反应 36.0h， 生成 2,2-Dimethyl-propionic acid (3Z,7E,11E)-16-methoxy-3,7,11-trimethyl-bicyclo[12.3.1]octadeca-1(17),3,7,11,14(18),15-hexaen-18-yl ester

  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.
