  Cyclizations and Rearrangements of Samarium Diiodide-Generated Vinyl Radicals

  摘要：

  Vinyl bromides 1, 5, 15, 20, 23, 27, 33a,b, 41a-c, 44a-c, 46a,b, 52a,b, 55a, 56a,b, and 60a,b react with samarium diiodide in THF and/or acetonitrile to give the corresponding vinyl radicals. Radicals 3, 7, and 16 afforded products deriving from cyclization on the adjacent triple bond in a 5-(pi-exo)exo, 6-(pi-endo)exo, and 6-(pi-exo)exo mode, respectively. Radical 7 undergoes competitive 1,5-hydrogen translocation. Vinyl radicals 21 and 24 readily cyclize on the proximal double bond, leading to 5- and 6-membered rings, respectively. Thienyl-substituted radical 28 leads to a product deriving from 5-exo cyclization on the thiophene ring and subsequent beta-fission of the C-S bond, whereas thienyl-substituted radicals 34a,b undergo almost exclusively 1,5-hydrogen translocation. Aryl-substituted radicals obtained from vinyl bromides 41, 44, 46, 52, and 55 do not form any products deriving from 5-exo or 6-exo cyclization (or ipso cyclization). Finally, naphthyl-substituted radicals 57a and 61a give only direct reduction products, whereas the radical 61b affords, in addition to the direct reduction product, a rearranged product deriving from a 1,3-radical migration of the naphthylthio group. Evidence is reported for the reduction of EWG-substituted benzene rings and thio-substituted naphthalene rings to radical anions, which can fragment on the side chain with the elimination of allyl radicals. alpha-Oxy(and alpha-thio)-substituted radicals deriving from 1,5-shift rearrange to alcohols (and thiols) through a Wittig rearrangement or a cyclization/fragmentation process.

  A dealkylative intercepted [2, 3]‐sigmatropic rearrangement reaction of allylic sulfides with 2, 2, 2‐trifluorodiazoethane (CF3CHN2) is reported, the commercially available and biocompatible catalyst hemin was found to efficiently catalyze this transformation across a diverse set of allylic sulfides with in situ generated CF3CHN2, providing excellent yields (up to 99%) under mild condition without

  据报道，烯丙基硫醚与2，2，2，2-三氟重氮乙烷（CF 3 CHN 2）发生脱烷基截获的[2，3]-σ重排反应，发现市售的生物相容性催化剂血红素可有效催化这一变化。原位生成的CF 3 CHN 2烯丙基硫化物，在温和条件下，无需惰性气体保护，即可提供优异的收率（高达99％）。此外，CF 3 CHN 2与其他常用的重氮试剂相比，对这一过程具有独特的反应性。这项工作扩大了由血红素催化的卡宾介导的转化范围，并引入了一种简明而通用的策略来开发有关有机硫化物的新反应可能性。

DFHZ-Tfs has been successfully employed in the Fe-catalyzed cyclopropanation and Doyle-Kirmse

  尽管挥发性官能化的重氮烷烃在有机合成中的重要性日益提高，但由于其难以处理以及存储和安全性问题，其安全生产和利用仍是一个艰巨的挑战。在这项研究中，我们开发了一种稳定的二氟乙醛N-三氟乙os（DFHZ-Tfs），作为一种操作安全的重氮替代物，可以原位释放两种低分子量的重氮烷烃，重氮乙醛（CHOCHN2）或二氟重氮乙烷（CF2 HCHN2）。在特定条件下的受控方式。DFHZ-Tfs已成功地用于铁催化的环丙烷化反应和Doyle-Kirmse反应中，从而突显了DFHZ-Tfs在有效构建包含CHO或CF2 H基团的分子框架中的合成效用。此外，

  Rh2(OAc)4-catalyzed [2,3]-sigmatropic rearrangement of sulfur ylides is reported. A series of cyclopropenes were successfully employed for [2,3]-sigmatropic rearrangement by a reaction with either allylic or propargylic sulfides. Under the optimized conditions, the reaction afforded the products in moderate to excellent yields. In these transformations, the vinyl metal carbenes generated in situ from the cyclopropenes
