  Rhodium(II)-Catalyzed Enantioselective C−H Functionalization of Indoles

  摘要：

  A catalytic, enantioselective method for the C-H functionalization of indoles by diazo compounds has been achieved. With catalytic amounts of Rh-2(S-NTTL)(4), the putative Rh-carbene intermediates from alpha-alkyl-alpha-diazoesters react with indoles at C(3) to provide alpha-alkyl-alpha-indolylacetates in high yield and enantioselectivity. From DFT calculations, a mechanism is proposed that involves a Rh-ylide intermediate with oxocarbenium character.

  We here describe a new, selective indium-promoted silver-mediated intermolecular oxidative 1,4-alkylarylation of 1,3-dienes with α-carbonyl alkyl bromides and N-heterocycles for producing functionalized N-heterocycles, which is characterized by its exquisitely controllable regio-/stereo-selectivity and excellent tolerance of functional groups. Mechanistically, the formation of the carbonyl-coordinated

  我们在此描述了一种新的，选择性的铟促进的银介导的1,3-二烯与α-羰基烷基溴化物和N-杂环的1,3-二烯间的分子间氧化1,4-烷基芳基化反应，以生产功能化的N-杂环，其特征在于其可控性很强区域/立体选择性和对官能团的优异耐受性。从机理上讲，羰基配位的η3-烯丙基-In复杂自由基中间体的形成是成功实现对1,4-双官能化和（E）-异构体的区域和立体选择性的关键因素。

  An expeditious metal free C-3 alkylation of indoles and its NIS-mediated deviation to indolo[2,3-b]quinolines is reported. This protocol, executed in aqueous HFIP has broad substrate scope and is well inclined towards the ideas of sustainable chemistry.
