  Total synthesis of (+)-asperazine

  摘要：

  The first total synthesis of the structurally novel cyclotryptophan alkaloid asperazine is reported. The central step in the synthetic sequence is a diastereoselective intramolecular Heck reaction in which the substituent controlling stereoselection is external to the ring being formed. This synthesis confirmed the structure of (+)- asperazine (1) proposed by Crews and co- workers and provided material for additional biological studies. The in vitro cytotoxicity originally reported for the marine isolate was not confirmed with synthetic (+)- asperazine. (c) 2007 Elsevier Ltd. All rights reserved.

  This work illustrates the reductive coupling of electron-rich aryl halides with tertiary alkyl halides under Ni-catalyzed cross-electrophile coupling conditions, which offers an efficient protocol for the construction of all carbon quaternary stereogenic centers. The mild and easy-to-operate reaction tolerates a wide range of functional groups. The utility of this method is manifested by the preparation

  这项工作说明了富电子芳基卤化物与叔烷基卤化物在 Ni 催化的交叉亲电偶联条件下的还原偶联，为构建所有碳四元立体中心提供了有效的方案。温和且易于操作的反应可耐受广泛的官能团。该方法的实用性通过环色胺衍生物的制备得到证明，其中成功掺入 7-吲哚基部分特别令人感兴趣，因为许多天然产物由这些关键支架组成。已经进行了 DFT 计算以研究提议的自由基链和双氧化加成途径，这为在溶液中发生的反应部分提供了有用的机理见解。
