• Facile Barton−McCombie Deoxygenation of Alcohols with Tetrabutylammonium Peroxydisulfate and Formate Ion
  作者：Hee Sock Park、Hee Yoon Lee、Yong Hae Kim

  DOI：10.1021/ol050886h

  日期：2005.7.1

  [reaction: see text]. A new method for efficient radical deoxygenation of alcohols is described for preparing bulk chemicals avoiding scale-up problems. Treatment of various thiocarbonyl derivatives with (Bu(4)N)(2)S(2)O(8) and HCO(2)Na in DMF afforded the corresponding deoxygenated products in excellent yields. The deoxygenation appears to be initiated by the transfer of a single electron to thiocarbonyl

  Starting from D-mannitol, we have prepared several C(2)-symmetric ethanotethered bis(alpha,beta-butenolides) and studied their [2+2] photocycloaddition reaction with ethylene. The protective groups of the central diol unit have a noticeable influence on the facial selectivity of the cycloaddition, the bis(trimethylsilyloxy) derivatives showing the highest diastereoselectivity. A theoretical conformational

  从D-甘露醇开始，我们准备了几个C（2）对称的乙醚双（α，β-丁烯内酯）对称并研究了它们与乙烯的[2 + 2]光环加成反应。中央二醇单元的保护基对环加成的面部选择性具有显着影响，双（三甲基甲硅烷基氧基）衍生物表现出最高的非对映选择性。基态底物的理论构象分析与实验观察到的非对面选择性非常吻合。该双（光环加合物）已被转化为对映纯环丁烷，该对映体是由乙烯与γ-羟甲基-α，β-丁烯内酯的光反应正式形成的，其中先前仅发现了中等的面部选择性。作为这些研究的应用，

  The bis-O-thioxocarbamate derivatives obtained from the reaction of vicinal diols with phenyl isothiocyanate are shown to be reduced with tris(trimethylsilyl)silane in the presence of azobisisobutyronitrile to afford the corresponding olefins in good yields. In this way, 2′,3′-didehydro-2′,3′-dideoxy analogs of adenosine, guanosine, inosine, cytidine and uridine were prepared by the radical-based deoxygenation
