  日期：2011.12.9

  With nitrogen too: The first catalytic [3+2] annulation of aminocyclopropanes with enol ethers is reported (see scheme; Phth=phthaloyl). The reaction worked with easily accessible phthalimidocyclopropanes using 5 mol % of SnCl4 in nearly quantitative yields. Polysubstituted cyclopentylamines, which are often present in bioactive compounds, were obtained with high diastereoselectivity and enantiospecificity

  日期：——

  Treatment of triisopropylsilyl enol ethers with PhIO/TMSN3/TEMPO (cat.)–45 °C results in 1,2-bis-azidonation, which appears to occur through a radical addition process; the 1-azido group can be replaced by carbon nucleophiles such as allyl, methyl, cyano, acetylene and acetonyl.

  DOI：10.1016/j.tetlet.2010.03.030

  日期：2010.5

  Trialkylsilyl triflimides generated in situ are unique catalysts for the electrophilic benzylation or allylation of trialkylsilylenol ethers or allyl trialkylsilanes with non-genotoxic alkylating reagents such as benzyl and allyl acetates. In most cases the reactions are fast at room temperature and yields are high. The reaction works particularly well with electron-rich benzyl donors including derivatives

  Carbon–carbon (C–C) bonds form the backbone of many important molecules, including polymers, dyes and pharmaceutical agents. The development of new methods to create these essential connections in a rapid and practical fashion has been the focus of numerous organic chemists. This endeavour relies heavily on the ability to form C–C bonds in the presence of sensitive functional groups and congested structural environments. Here we report a chemical transformation that allows the facile construction of highly substituted and uniquely functionalized C–C bonds. Using a simple iron catalyst, an inexpensive silane and a benign solvent under ambient atmosphere, heteroatom-substituted olefins are easily reacted with electron-deficient olefins to create molecular architectures that were previously difficult or impossible to access. More than 60 examples are presented with a wide array of substrates, demonstrating the chemoselectivity and mildness of this simple reaction. Highly substituted carbon–carbon bonds are constructed using a simple iron catalyst and an inexpensive silane: more than 60 examples of this reaction — in which heteroatom-substituted olefins are reacted with electron-deficient olefins — are presented. This paper reports the development of a new type of carbon–carbon bond forming reaction that allows for the simple construction of molecules that were previously either impossible or laborious to access. The procedure exploits an interaction between heteroatom-substituted olefins and electron-deficient olefins to construct highly substituted carbon–carbon bonds using a simple iron catalyst and an inexpensive silane. The authors present than sixty examples of this reaction, covering a broad range of substrates. This reaction is of relevance to the design of organic compounds including polymers, dyes, and pharmaceutical agents and semiconductors.
