  描述：

  1,3-Dibenzyl-4-bromopyrrole-2,5-dione 、 4-[(3-methyl-2-butenyloxy)phenyl]tributylstannane 在 四(三苯基膦)钯 作用下， 以93%的产率得到N-benzyl-3-benzyl-4-[4-(3-methyl-2-butenyloxy)phenyl]maleimide

  名称：

  Total synthesis of (±)-camphorataimides and (±)-himanimides by NaBH4/Ni(OAc)2 or Zn/AcOH stereoselective reduction

  摘要：

  Maleic anhydride 1 of Antrodia camphorate, which can be isolated from Chinese herbal medicine, is achieved in which the longest linear sequence is only five steps, in 40% overall yield from commercially available succinic anhydride. The crucial antrodimides 3 and 2 can be readily transformed by the chemoselective reduction with Zn/AcOH and NaBH(4)/Ni(OAc)(2).4H(2)O to afford the naturally occurring camphorataimides, 4 and 5, in high yields as well, respectively. This synthetic strategy can also be modified to give access to a variety of different maleic acid derivatives, himanimides 6-8. (c) 2008 Elsevier Ltd. All rights reserved.
