Synthesis of 4-functionalized-1H-indoles from 2,3-dihalophenols
作者:Roberto Sanz、Verónica Guilarte、Nuria García
DOI:10.1039/c004360e
日期:——
A new synthesis of 4-halo-1H-indoles has been developed from easily available 2,3-dihalophenol derivatives. The key steps are Smiles rearrangement and a one-pot or stepwise Sonogashira coupling/NaOH-mediated cyclization. Subsequent functionalization allows access to a wide variety of 2,4- or 2,3,4-regioselectively functionalized indoles.

2,3-Dihaloanilines have been proved as useful starting materials for synthesizing 4-halo-1H-indoles. Subsequent or in situ functionalization of the prepared haloindoles allows the access to a wide variety of 2,4- or 2,3,4-regioselectively functionalized indoles in good overall yields. As no efficient synthetic routes to 2,3-dihaloanilines have been described in the literature, different approaches
A Practical, One-Pot Synthesis of Highly Substituted Thiophenes and Benzo[<i>b</i>]thiophenes from Bromoenynes and <i>o</i>-Alkynylbromobenzenes

日期:2011.10.7
An efficient synthesis of thiophenes and benzo[b]thiophenes has been developed from easily available bromoenynes and o-alkynylbromobenzene derivatives. This novel one-pot procedure involves a Pd-catalyzed C–S bond formation using a hydrogen sulfide surrogate followed by a heterocyclization reaction. Moreover, in situ functionalization with selected electrophiles further expands the potential of this
由容易获得的溴代炔和邻炔基溴苯衍生物已开发出噻吩和苯并[ b ]噻吩的有效合成方法。这种新颖的一锅法涉及使用硫化氢替代物进行钯催化的C–S键形成,然后进行杂环化反应。此外,用选定的亲电试剂进行原位官能化进一步扩大了该方法在制备相应的高度取代的硫杂环化合物方面的潜力。
Regioselective Synthesis of 4- and 7-Alkoxyindoles from 2,3-Dihalophenols: Application to the Preparation of Indole Inhibitors of Phospholipase A<sub>2</sub>

An efficient and regioselectivesynthesis of 4- and 7-alkoxyindoles has been developed from commercially available starting materials such as 3-halophenols and 3-chloroanisole. Directed ortho-metalation followed by two palladium-catalyzed processes, a Sonogashira coupling and a tandem amination/cyclization reaction, allows the synthesis of regiochemically pure 4- and 7-substituted indoles. This strategy
