  • Regioselectivity in the Intramolecular Heck Reaction of a Series of Cyclic Sulfonamides: An Experimental and Computational Study
    作者:Kimberly Geoghegan、Paul Evans、Isabel Rozas、Ibon Alkorta
    DOI:10.1002/chem.201201359
    日期:2012.10.15
    Regioselectivity in the intramolecular Heck reaction of a series of N‐sulfonyl‐2,5‐dihydro‐3‐substituted pyrroles was studied. These substrates are unbiased in terms of the formed ring size of the new heterocycle. Results indicate that high levels of regioselectivity are observed under a range of conditions, and that there is an underlying propensity for carbon–carbon bond formation at the most hindered
    研究了一系列N-磺酰基-2,5-二氢-3-取代吡咯在分子内Heck反应中的区域选择性。这些衬底在新杂环形成的环尺寸方面没有偏见。结果表明,在一定条件下观察到了很高的区域选择性,并且在烯烃最受阻的末端存在潜在的碳-碳键形成趋势。对于两个示例(3 Me和3 t Bu),进行了DFT计算,结果表明,在这两种情况下,对于碳酸盐的建模过渡态,对于实验上优选的异构体,在能量上都较低。
  • Ammonium formate-based one-pot reductive Heck reactions for the construction of cyclic sulfonamides
    作者:Aisha Khalifa、Lorna Conway、Kimberly Geoghegan、Paul Evans
    DOI:10.1016/j.tetlet.2017.10.053
    日期:2017.11
    A modified method is reported for the conversion of unsaturated sulfonamides into their cyclic saturated counterparts. This method utilises a single palladium catalyst for an intramolecular Heck reaction and subsequent transfer hydrogenation, which is achieved in one-pot following the addition of ammonium formate. Accordingly, a range of fourteen structural variations are reported and under optimal
    报道了一种改进的方法,用于将不饱和磺酰胺转化为其环状饱和对应物。该方法利用一种单一的钯催化剂进行分子内Heck反应和随后的转移氢化,这是在添加甲酸铵后一锅内完成的。因此,报道了十四种结构变化的范围,并且在最佳条件下以通常良好至优异的产率生成加合物。值得注意的是,在化合物28和29的情况下,可以实现对差异取代的二烯的区分,并且仅观察到该过程在空间上受阻更大的前体32下失败。
  • An Investigation into the One-Pot Heck Olefination−Hydrogenation Reaction
    作者:Kimberly Geoghegan、Susan Kelleher、Paul Evans
    DOI:10.1021/jo200023r
    日期:2011.4.1
    Herein is described an operationally simple process concerning the observation that, following either inter-, or intramolecular Heck olefination, stirring of the so formed substituted alkenyl product under an atmosphere of hydrogen efficiently effects alkene hydrogenation. Overall this two-operation, one-pot "reductive Heck" sequence is notable since direct reductive Heck processes, using additives such as formate salts, are restricted to a limited range of substrates. In total 25 examples are reported (yields ranging from 0 to 95%), which were selected in order to probe the scope and limitations of this method. Finally, the utility of this sequence was demonstrated in a short synthesis of the calcimimetic agent, cinacalcet.
  • Halonium Ion Triggered Rearrangement of Unsaturated Benzo-Annulated Bi- and Tricyclic Sulfonamides
    作者:Kimberly Geoghegan、Shaun Smullen、Paul Evans
    DOI:10.1021/jo401888f
    日期:2013.10.18
    The halonium ion mediated 1,2-Wagner–Meerwein-type rearrangement of a series of benzo-fused bi- and tricyclic sulfonamides is reported. During this rearrangement the carbon–carbon bond that migrates was selectively set in the intramolecular Mizoroki–Heck (IHR) synthesis of the starting materials. Consequently, this method constitutes a means to access the regioisomeric series of cyclic sulfonamides
    ha离子介导的一系列苯并稠合的双环和三环磺酰胺的1,2-Wagner-Meerwein型重排。在这种重排过程中,迁移的碳-碳键被选择性地设置在起始材料的分子内Mizoroki-Heck(IHR)合成中。因此,该方法构成了访问在Mizoroki-Heck反应中未观察到的环状磺酰胺类区域异构体的方法。
