  A Convenient Metal-Free Reagent for the Generation and Capture of Trifluoromethanethiol

  摘要：

  0-Octadecyl-S-trifluorothiolcarbonate is a cheap and storable crystalline source of trifluoromethanethiol that can be prepared in two steps on a multigram scale from trifluoroacetic anhydride and sodium 0-octadecyl-dithiocarbonate (xanthate). It reacts directly with gramines or with alpha-bromoketones and -esters in the presence of KF and pyrrolidine to give the corresponding trifluoromethyl sulfides in generally high yield.

  A radical based synthesis of a broad variety of protected enantiopure α-amino acids, including fluorinated derivatives, is described. The radical addition furnishes naturally latent mercapto-α-amino acids ideally equipped for native chemical ligation.

  atom abstraction and delivers a vast array of highly functional geminal bis(boronates). The ability to assemble geminal bis(boronates) bearing polar functional groups not readily obtained through existing methods is particularly noteworthy. This approach also opens up access to geminal bis(boronyl) cyclopropanes and geminal bis(boronyl) tetrahydroquinolines.

  将二硫代碳酸酯自由基加成到1,1-双（硼基）-3-丁烯和相关的烯烃中，不会造成碎片或氢原子抽象的复杂情况，并且可提供大量高功能双键双（硼酸酯）。通过现有方法不易获得的带有双极性基团的双（硼酸酯）双宝石的组装能力特别值得注意。这种方法也为双子双（硼烷基）环丙烷和双（双硼烷基）四氢喹啉提供了可能。
• Radical Instability in Aid of Efficiency: A Powerful Route to Highly Functional MIDA Boronates
  作者：Béatrice Quiclet-Sire、Samir Z. Zard

  DOI：10.1021/jacs.5b03893

  日期：2015.6.3

  The inability of the sp(3) boron in MIDA boronates to stabilize an adjacent radical makes possible the efficient addition of a wide array Of xanthates to vinyl MIDA boronate, leading to highly functionalized and diverse aliphatic organoboron structures. The lack of radical Stabilization also allows the exchange Of the Xanthate in the adducts with a bromine. In one case, the bromine was substituted to generate a cyclopropyl MIDA derivative.

  Unprecedented examples of a synthetically useful radical ring closure onto a pyrimidine nitrogen leading to novel, highly functionalized bi- and tricyclic pyrimidone structures are reported. An unexpected hydrogen atom translocation prior to the cyclization step was observed in some cases.
