  描述：

  N-methyl-5-bromopiperonylamine 在 盐酸 、 碳酸氢钠 作用下， 以 甲醇 为溶剂， 反应 16.0h， 生成 9-bromo-6-methyl-7,8-dihydro-5H-[1,3]dioxolo[4,5-g]isoquinolin-8-ol
  参考文献：
  名称：

  Three complementary methods offering access to 5-substituted 1,2,3,4-tetrahydroisoquinolines

  摘要：

  The scope and limitations of three independent though related routes leading to 5-substituted tetrahydroisoquinolines are explored : the Pidet-Spengler type cyclization of ortho-substituted 2-phenylethylamines, the Pomeranz-Fritsch type cyclization of meta-substituted benzylamines and the electrophilic trapping of 5-lithiated 4-lithiooxytetrahydroquinolines. The introduction of the substituent relies in all three cases on a neighboring group assisted site selective metalation step. (C) 1998 Elsevier Science Ltd. All rights reserved.
