  描述：

  methyl 2-amino-3-methoxy-6-methylbenzoate 在 正丁基锂 、 二异丙胺 作用下， 以 四氢呋喃 、 正己烷 为溶剂， 反应 4.5h， 以40%的产率得到methyl 2,3-dihydro-2,4-dimethyl-1-formyl-7-methoxy-3-oxo-1H-indole-2-carboxylate
  参考文献：
  名称：

  Synthetic studies on duocarmycin. 1. Total synthesis of dl-duocarmycin A and its 2-epimer

  摘要：

  The title synthesis was first achieved by employing novel methoxycarbonylation of the C-4-position of the 5-aminoindoline by way of the isatin and subsequent Dieckmann cyclization to the methyl 2-methylindoxyl-2- carboxylate as key steps. In vitro cytotoxicity assay against P388 murine leukemia obviously disclosed that cytotoxicities of the synthesized compounds are comparable and almost half of that of natural (+)-duocarmycin A.
