以前未开发的将格利雅(Grignard)添加到羟吲哚中的方法通过一锅芳构化驱动的脱水途径,以高收率提供了一种区域特异性的方法,用于2-和2,3-二取代的吲哚衍生物。这种方法可以方便地制备用作烯丙基[1,2- a ]吲哚和咔唑的正交合成的闭环复分解(RCM)前体的二烯丙基吲哚。该方法的合成效用通过微管蛋白抑制剂和天然存在的咔唑生物碱的合成来说明。

Gold‐ringing! Modification of the substitution at C2 drives an entirely different cyclization of N‐tethered allenylindoles. An efficient cycloisomerization takes place for the case of R being hydrogen, that is, compatible with additional functional groups. A methyl at C2 precludes this possibility and launches a stepwise process that can be tuned to yield macrocyclic trimers.

Compounds and pharmaceutical compositions that modulate kinase activity, including mutant EGFR and mutant HER2 kinase activity, and compounds, pharmaceutical compositions, and methods of treatment of diseases and conditions associated with kinase activity, including mutant EGFRand mutant HER2 activity, are described herein.
regiospecific approach to 2- and 2,3-disubstituted indole derivatives in high yields via a one-pot aromatization driven dehydration pathway. This method allows a convenient preparation of diallyl indoles that are used as ring-closing metathesis (RCM) precursors for the orthogonal synthesis of pyrido[1,2-a]indoles and carbazoles. The synthetic utility of this method is illustrated by the synthesis of a microtubulin

Pt versus Au: Platinum‐catalysed addition of nucleophiles to allenes follows a distinctly different pathway to the process catalysed by gold(I) complexes; the platinum catalyst leads to different products with indoles involving a bisindolylation reaction, whereas gold(I) gives allyl indoles from a single addition (see scheme).
Pt vs Au:铂催化的亲核试剂向丙二烯的加成遵循截然不同的金(I)络合物催化的过程。铂催化剂可生成涉及双吲哚基化反应的吲哚的不同产物,而金(I)只需一次添加即可生成烯丙基吲哚(参见方案)。
