• 1,1,1,3,3,3-Hexafluoroisopropanol: A Recyclable Organocatalyst for<i>N</i>-Boc Protection of Amines
  作者：Akbar Heydari、Samad Khaksar、Mahmood Tajbakhsh

  DOI：10.1055/s-2008-1067272

  日期：2008.10

  A simple and efficient protocol for the chemoselective mono-N-Boc protection of various structurally diverse amines with di-tert-butyl dicarbonate using 1,1,1,3,3,3-hexafluoroisopropanol (HFIP) as solvent and catalyst is described. The catalyst can be readily separated from the reaction products and recovered for direct reuse. No competitive side reactions such as formation of isocyanate, urea, and N,N-di-Boc were observed. α-Amino alcohols afforded the N-Boc derivatives without oxazolidinone formation.

  Résumé An efficient and practical protocol for the chemoselective N-Boc protection of various structurally different aryl, aliphatic and heterocyclic amines was carried out with (Boc)2O using protic 1, 1, 3, 3-tetra-methylguanidinium acetate (10 mol%) as recyclable catalyst under solvent free condition at ambient temperature. No competitive side reactions (isocyanate, urea and N, N-di-Boc) were observed. α-Amino alcohols afforded the N-Boc-derivative without oxazolidinone formation.

  Enamines and enol ethers are versatile synthons for chemical synthesis. While several methods have been developed to access such molecules, prefunctionalized starting materials are usually required, and direct desaturation methods remain rare. Herein, we report direct desaturation reactions of N-protected cyclic amines and cyclic ethers using a mild I(III) oxidant, PhI(OAc)2, and an electron-deficient

  烯胺和烯醇醚是用于化学合成的通用合成子。尽管已经开发出几种方法来接近这些分子，但是通常需要预官能化的起始材料，并且直接去饱和方法仍然很少。在这里，我们报告了使用温和的I（III）氧化剂PhI（OAc）2和电子不足的五氟苯基卟啉锰Mn（TPFPP）Cl的N-保护的环胺和环醚的直接去饱和反应。该系统显示出各种环状胺和醚的α，β-去饱和的高效率。机理探针表明，去饱和反应是通过最初的α-CH羟基化途径发生的，这可以保护产物免于过氧化。

  C(sp3)–heteroatom bonds from strong C–H bonds has been reported6,7. Additionally, valuable technologies have been developed for the formation of carbon–carbon bonds from the corresponding C(sp3)–H bonds via substrate-directed transition-metal C–H insertion8, undirected C–H insertion by captodative rhodium carbenoid complexes9, or hydrogen atom transfer from weak, hydridic C–H bonds by electrophilic

  尽管过渡金属催化的交叉偶联方法取得了广泛的成功，但 sp3 杂化碳原子的反应仍然存在相当大的局限性，大多数方法依赖于预官能化的烷基金属或溴化物偶联伙伴 1,2。尽管使用天然官能团（例如，羧酸、烯烃和醇）通过扩大潜在原料的范围提高了此类转化的整体效率3-5，但碳氢（C-H）键的直接官能化——有机分子中最丰富的部分——代表了一种更理想的分子构建方法。近年来，已经报道了从强 C-H 键形成 C(sp3)-杂原子键的一系列令人印象深刻的反应6,7。此外，已经开发出有价值的技术，用于通过底物导向的过渡金属 C-H 插入 8、通过捕获性铑卡宾配合物 9 的非定向 C-H 插入或氢原子转移从相应的 C(sp3)-H 键形成碳-碳键通过亲电开壳物质 10-14 从弱的氢化 C-H 键中提取。尽管取得了这些进展，但尚未实现用于将强中性 C(sp3)-H 键与芳基亲电试剂偶联的温和通用平台。在这里，我们描述了
