  Solving the puzzles: Total synthesis played a key role in the elucidation of the stereochemistry and verification of the constitution of the complex polymeric natural product psychotetramine. The route features three powerful assembly processes that enabled four rounds of total synthesis‐guided structure determination. The pursuit of this alkaloid also led to an improved procedure for indole–aniline

  C3–N linkage comprise the core of many biologically active natural products, but many methods toward their synthesis are limited by the sterics or electronics of the product. We report a single electron-based approach for the synthesis of this scaffold and demonstrate high-yielding aminations, regardless of electronic or steric demands. The transformation uses copper wire and isopropanol to promote

• Scalable Total Syntheses of <i>N</i>-Linked Tryptamine Dimers by Direct Indole−Aniline Coupling: Psychotrimine and Kapakahines B and F

  DOI：10.1021/ja1009458

  日期：2010.5.26

  This report details the invention of a method to enable syntheses of psychotrimine (1) and the kapakahines F and B (2, 3) on a gram scale and in a minimum number of steps. Mechanistic inquiries are presented for the key enabling quaternization of indole at the C3 position by electrophilic attack of an activated aniline species. Excellent chemo-, regio-, and diastereoselectivities are observed for reactions with o-iodoaniline, an indole cation equivalent. Additionally, the scope of this reaction is broad with respect to the tryptamine and aniline components. The anti-cancer profiles of 1-3 have also been evaluated.
• Total Synthesis of (±)-Psychotrimine
  作者：Timothy Newhouse、Phil S. Baran

  DOI：10.1021/ja8042307

  日期：2008.8.1

  A new process for the union of anilines with tryptamine derivatives has been developed, furnishing C-3 quaternized pyrroloindoline architectures. This chemoselective coupling of a tryptamine with 1.2 equiv of 2-iodoaniline proceeds efficiently on a gram-scale using only the simple reagents N-iodosuccinimide and triethylamine. Using this new reaction, the complex natural product psychotrimine has been fashioned with a rare level of efficiency and practicality. From a readily available bromotryptamine, only four steps (41-45% overall isolated yield) are necessary to procure gram quantities of the natural product. Functional group manipulations, protecting group chemistry, and unnecessary redox fluctuations have been minimized.
