  Preparation ofN-nitrohydroxylamines by direct nitration

  摘要：

  The possibilities for stabilization of compounds with the A-B-NO2 fragment, where A is an atom containing a lone electron pair, were examined. It was shown that N-methyl-O-2,4-dinitro- and 2,4,6-trinitrophenylhydroxylamines undergo nitration with nitronium tetrafluoroborate or with a mixture of nitric acid and acetic anhydride to give the corresponding N-nitrohydroxylamines in high yields. N-Nitro-2,4-dinitrohydroxylamine that contains no methyl group at the nitrogen atom is unstable and forms a product of O-alkylation upon reaction with diazomethane.

  derivatives as a synthetic building block, no practical methods have emerged for direct synthesis of this compound class from unfunctionalized olefins. Here, we present a mild, versatile method for the direct stereospecific conversion of structurally diverse mono-, di-, tri-, and tetrasubstituted olefins to N-H aziridines using O-(2,4-dinitrophenyl)hydroxylamine (DPH) via homogeneous rhodium catalysis

  未修饰的氮丙啶 已经开发了多种催化方法来制造氮丙啶——作为多功能合成中间体的应变三角形碳-氮-碳环。然而，大多数需要用随后不方便去除的磺酰基保护氮前体。贾特等人。（第 61 页；参见 Türkmen 和 Aggarwal 的 Perspective）使用羟胺衍生物作为氮源以及已建立的铑催化剂来制备各种未保护的氮丙啶，其中氮仅与氢或甲基键合。三角形碳氮环的路线避免了在氮前体上放置难以去除的保护基团。尽管 NH 氮丙啶基序在生物活性天然产物中普遍存在，并且这种未受保护的母体结构作为合成构件比 N 受保护的衍生物具有明显的优势，但尚未出现从未官能化的烯烃直接合成此类化合物的实用方法。在这里，我们提出了一种温和、通用的方法，通过均相铑催化使用 O-(2,4-二硝基苯基) 羟胺 (DPH) 将结构多样的单、二、三和四取代烯烃直接立体定向转化为 NH 氮丙啶不含外部氧化剂。该方法操作简单（即一锅法）、

  visible-light-induced synthesis of functionalized pyrroloindolines via a radical cascade reaction is reported. The reaction shows a broad substrate scope and highlights the mild nature of the reaction conditions. A range of substitutions on indole aromatic rings and N-centers is well tolerated, including a free allylic alcohol. Relying on the strategy, a rapid synthesis of (±)-flustraminol B was achieved.
