  A one-pot three-component reaction for the preparation of highly functionalized tryptamines

  摘要：

  We have developed a general one-pot method to provide highly functionalized tryptamine derivatives, via a Fischer indole type pathway. In this article, we demonstrate optimal conditions for a one-pot indole synthesis, allowing for the synthesis of a broad scope of 2-methyl tryptamine derivatives and a precursor for the synthesis of the core structure of some akuammiline alkaloids. Additionally, further modification of the indole products is described. Published by Elsevier Ltd.

  An efficient, one-pot reductive alkylation of indoles with N-protected aminoethyl acetals in the presence of TES/TFA is reported. It represents the first general method for the direct synthesis of tryptamine derivatives from indoles and nitrogen-functionalized acetals. This convergent and versatile approach employs safe and inexpensive reagents, proceeds under mild conditions, and tolerates several

  报道了在TES / TFA存在下用N-保护的氨基乙基缩醛对吲哚进行有效的一锅还原烷基化反应。它代表了从吲哚和氮官能化的缩醛直接合成色胺的首个通用方法。这种融合和通用的方法使用安全且便宜的试剂，可在温和条件下进行，并可以耐受多个官能团。该新方法可有效地用于Luzindole（一种参考MT2选择性褪黑激素受体拮抗剂）和褪黑素的克级合成。

  A new method for the synthesis of 2- and 3-substituted indolylalkylamides, derivatives of melatonin, from arylhydrazines and amidoketones by the Fischer reaction was elaborated. The amidoketones can be easily prepared from cyclic imines by reaction with acylpyridinium chloride. This method is a one-step synchronous creation of the selected alkylamide fragment and the indole core. Variation of the arylhydrazines
