• Ruthenium-Catalyzed Rearrangement of <i>cis</i>-1-Ethynyl-2-vinyloxiranes to Substituted Phenols
  作者：Rai-Shung Liu、Shambabu Maddirala、Arjan Odedra、Bhanu Taduri

  DOI：10.1055/s-2006-926255

  日期：——

  Catalytic cyclization of cis-1-ethynyl-2-vinyloxiranes was implemented with TpRuPPh3(CH3CN)2PF6 catalyst (10 mol%), to give 2,6-disubstituted phenols in reasonable yields. Under similar conditions, 1,1,2,2-tetrasubstituted oxirane gave the 2,3,6-trisubstituted phenol with skeleton reorganization. On the basis of 2H- and 13C-labeling results, we propose that the reaction mechanism involves electrocyclization of ruthenium-vinylidene intermediate with cleavage of the carbon-oxygen bond of the epoxide.

  使用TpRuPPh3(CH3CN)2PF6催化剂（10 mol%）实施了顺式-1-乙炔基-2-乙烯氧杂环丁烷的催化环化反应，合理产率地得到了2,6-二取代苯酚。在类似的条件下，1,1,2,2-四取代氧杂环丁烷通过骨架重排生成了2,3,6-三取代苯酚。基于2H和13C标记结果，我们提出反应机制涉及钌-乙烯叉中间体的电子环化以及环氧化物碳氧键的断裂。
