  描述：

  [5-(triphenylmethyloxy)-1-pentyl] 2-(prenyloxymethyl)benzoate 在 4-二甲氨基吡啶 、 溶剂黄146 、 三乙胺 作用下， 以 二氯甲烷 为溶剂， 反应 7.5h， 生成 1,5-pentanediol chloroacetyl 2-(prenyloxymethyl)benzoyl ester
  参考文献：
  名称：

  2-(Prenyloxymethyl)benzoyl (POMB) group: a new temporary protecting group removable by intramolecular cyclization

  摘要：

  2-(Prenyloxymethyl)benzoates can be prepared from alcohols and readily available 2-(prenyloxymethyl)benzoic acid by standard acylation techniques or by Mitsunobu reaction with inversion of configuration. The POMB group can be cleaved first by oxidative removal of the prenyl group with DDQ followed by lactonization with expulsion of the alcohol catalyzed by Yb(OTf)(3). These reaction conditions are compatible with the presence of a large number of common protecting groups. (c) 2007 Elsevier Ltd. All rights reserved.
