  Radical Chain Reactions of α-Azido-β-keto Esters with Tributyltin Hydride. A Novel Entry to Amides and Lactams through Regiospecific Nitrogen Insertion

  摘要：

  A variety of acyclic and carbocyclic alpha-azido-beta-keto esters have been readily prepared from the parent dicarbonyl compounds, and their radical chain reactions with tributyltin hydride have been investigated. These reactions normally result in efficient production of alkoxycarbonyl-substituted amides and lactams and thence provide a new, useful method for regiospecific nitrogen insertion of keto ester compounds. The likely mechanism entails initial addition of tributylstannyl radical to the azido moiety to give a stannylaminyl radical, which readily undergoes intramolecular three-membered cyclization onto the ketone group to form an alkoxyl radical. The alkoxyl radical then undergoes regiospecific beta-scissian to form a stable ring-opened radical that is eventually reduced by tributyltin hydride to propagate the chain. With certain substrates, concomitant deazidation occurs to an important extent. This process, which is unusually observed in radical reactions of alkyl azides, is ascribed to addition of the stannyl radical to the terminal azido nitrogen; subsequent fragmentation of the ensuing 1,3-triazenyl adduct gives stannyl azide and a deazidated alkyl radical, resonance-stabilized by the adjacent carbonyl groups. The radical reactions of 2-azido-2-(ethoxy-carbonyl)-1-tetralone with allyltributylstannane and allyltriphenylstannane have also been investigated with the (missed) aim to achieve nitrogen insertion and concomitant allylation.

  1,3-二羰基的实际叠氮化

  摘要：

  已开发出一种操作简单的直接叠氮化1,3-二羰基化合物的方法。使用叠氮化钠和基于碘的氧化剂（例如I 2或2-碘氧基苯甲酸（IBX）-SO 3 K / NaI ），反应可在环境条件下轻松进行。尤其是，后一种方法作为一种新型且平衡良好的氧化剂，具有出色的官能团耐受性和底物范围，因此可以使用各种叔二叠氮基和2,2-双叠氮基1,3-二羰基化合物使用传统方法将更难以访问。由于含叠氮化物的产品容易与炔烃进行1,3-偶极环加成反应，因此我们的报告提出了一条通往敏感复杂分子类似物的新途径。

  Iron-catalysed 1,2-acyl migration of tertiary α-azido ketones and 2-azido-1,3-dicarbonyl compounds provides a simple and atom-economical approach toward enamides and isoquinolones. This paper reports two catalyst systems for these transformations which employ iron(II) complexes [Fe(dpbz)]Br2 (dpbz = 1,2-bis(diphenylphosphino)benzene) and FeBr2/Et3N, respectively. [Fe(dpbz)]Br2 was found to be highly

  铁催化的α-叠氮基酮和2-叠氮基-1,3-二羰基化合物的1,2-酰基迁移为酰胺和异喹啉酮提供了一种简单且原子经济的方法。本文报道两种催化剂体系用于这些转化其采用铁（II）配合物的[Fe（dpbz）]溴2（dpbz = 1,2-双（二苯基膦基）苯）和FeBr 2 / ET 3 N，分别。发现[Fe（dpbz）] Br 2在将2-叠氮基-2,3-二氢-1 H-茚满-1-酮转化为异喹诺酮方面非常有效。另一方面，由于Et 3的有益作用，FeBr 2 / Et 3 N的试剂组合具有更宽的催化范围N.后一种催化剂体系可使2-叠氮基-2-甲基-1,3-二羰基化合物在温和条件下以良好的收率转化为相应的酰胺。

  transformed into enamides by treatment with FeBr2 at elevated temperature in DMF. The reaction proceeds via 1,2-benzoyl migration from α-carbon to the nitrogen atom, accompanied by expulsion of a nitrogen molecule. This protocol is suitable for the synthesis of N-(cyclopent-1-en-1-yl)benzamides, N-(cyclohex-1-en-1-yl)benzamides, and N-benzoyl-α-methyl enamines and provides a convenient approach toward isoquinolones
