  摘要：

  TBAF-catalyzed [3 + 2] cycloaddition reactions of 2-aryl-1-cyano- or 2-aryl-1-carbethoxy-1-nitroethenes 1 with TMSN3 under SFC allow the corresponding 4-aryl-5-eyano- or 4-aryl-5-carbethoxy-1H-1,2,3-triazoles 2 to be prepared under mild reaction conditions and with good to excellent yields (70-90%). The proposed protocol does not require dried glassware or inert atmosphere.

  the postsynthetic modification of Zr‐based metal organic frameworks (MOFs) containing chiral NNN‐pincer ligands based on aminopyridineimines, as well as the subsequent formation of (NNN)‐M‐Zr‐MOF complexes (M=Rh, Ir). With these new multifunctional materials, we performed a cascade of condensation reactions followed by hydrogenation of the resulting double bond. If the condensation reaction occurs between

  我们描述了Zr基金属有机骨架（MOF）的合成后修饰，该骨架包含基于氨基吡啶亚胺的手性NNN钳形配体，以及随后形成的（NNN）‐M‐Zr‐MOF配合物（M = Rh，Ir）。使用这些新的多功能材料，我们进行了一系列的缩合反应，然后氢化所得的双键。如果醛与硝基乙酸乙酯之间发生缩合反应，则（NNN）–M–Zr–MOF络合物催化一锅合成硝基烯烃，其中Zr IV Lewis位点的作用类似于常用的Ti IV。在均相催化中。这些多功能杂化催化剂甚至在反应后仍保持其晶体构架，并且可以通过过滤从反应混合物中轻松分离出它们，并重复使用数次而不会显着降低活性。而且，没有来自浸出的活性物质的贡献，并且仅在固体催化剂存在下才有可能转化。

  Efficient one-pot methods for the synthesis of variously functionalised conjugated nitro alkenes have been reported. Despite the utility in different fields of these compounds, only a few multi-step syntheses have been reported in the literature, giving the target compounds in low overall yields. α-Nitro acrylates or cinnamates, α-nitro α,β-unsaturated ketones and, most importantly, aromatic and heteroaromatic

  The synthesis of five-membered rings using fluoromethylene transfer chemistry is an attractive method for building fluorinated products of high value. This work demonstrates for the first time that one-fluorine-one-carbon modification of a substrate could be a viable strategy to access monofluorinated five-membered rings. The synthetic methodology was developed to access monofluorinated isoxazoline-N-oxides

  The addition of alkyl or aryl thiols to alpha-nitro or beta-nitrocinnamate in the presence of base provided Michael addition products. In the case of beta-nitro compounds reaction occurred via the formation of anti-Michael adducts. Selective nitro reduction of alpha-nitroadducts gives access to beta-thio-alpha-amino acid derivatives.
• Selective Amination Reactions of α-Nitro Aryl and Heteroaryl Enoates
  作者：Stefania Fioravanti、Lucio Pellacani、Maria Cecilia Vergari

  DOI：10.1021/jo4012859

  日期：2013.8.16

  Highly functionalized tetrasubstituted alkenes were obtained by an unexpected amination reaction promoted by ethyl nosyloxycarbamate on various alpha-nitro aryl and heteroaryl enoates. A nitrene is likely the aminating species responsible for the observed insertion reaction leading to (E)-beta-amino alpha-nitro enoates as the major products, regardless of the substrate configuration. The compounds, bearing two nitrogenous functional groups in different oxidation states, can be regarded as interesting synthons. In contrast, aziridination was observed for alpha-nitro alkyl enoates or beta-nitro allylic alcohols.
