  Preparation and reactivity of highly functionalized organometallics at the .alpha. position of oxygen or nitrogen

  摘要：

  Alpha-Halogenoalkyl carboxylates (FG-R1CH(X)(OCOR2); FG = COOR, CN, SR; X = I, Br) were readily prepared by the addition of an acid chloride or bromide (R2COX; X = Br or Cl) to an aldehyde (FG-RCHO) in the presence of a catalytic amount of ZnCl2. They insert efficiently zinc dust in THF-DMSO (X = Br, 8-10-degrees-C, 6-10 h) affording the corresponding zinc organometallics at the a position to oxygen FG-RCH(ZnBr)(OAc). After the addition of the THF-soluble copper salt CuCN.2LiCl, the corresponding copper reagents FG-RCH(Cu(CN)ZnBr)(OAc) are formed and reacted with various classes of electrophiles such as acid chlorides, aldehydes, enones, allylic and alkynyl halides, activated alkynes, nitro olefins and alkylidenemalonates providing polyfunctional molecules in excellent yields. Similarly, zinc organometallics at the a position to the nitrogen of cyclic imides were prepared by the zinc insertion to cyclic alpha-chloromethyl (or alpha-chloroethyl) imides. After their transmetalation to the corresponding copper organometallic ((R1CO)2NCH(R)(Cu(CN)ZnCl); R = Me or H), they were reacted with allylic and alkynyl halides and ethyl propiolate affording polyfunctional imides. The reaction of cyclic N-(chloromethyl)imides with aldehydes in the presence of chromium(II) chloride in THF furnishes protected amino alcohols in 36-95% yield.

  in organic molecules. Methylene C–H bonds are among the most difficult chemical bonds to selectively functionalize because of their abundance in organic structures and inertness to most chemical reagents. Their selective oxidations in biosynthetic pathways underscore the power of such reactions for streamlining the synthesis of molecules with complex oxygenation patterns. We report that an iron catalyst

  二级选择性有机分子主要由亚甲基（二级）CH2 基团的环和链组成，间歇性地装饰有氧或氮中心以及连接处更重取代的碳。如果沿着框架的任何特定亚甲基中的 C-H 键可以作为选择性修饰的目标，那么合成转化将是最有效的。然而，在大多数情况下，这些碳中心被证明非常难以区分用于反应目的。Chen 和 White (p. 566) 现在表明，铁催化剂可以引导过氧化物优先氧化一系列复杂分子中的特定二级 C-H 键，并具有合理的效率。观察到的选择性遵循与目标位点的电子和空间环境相关的可预测趋势。铁催化剂显示出对有机分子中二级 C-H 键氧化的选择性。亚甲基 C-H 键是最难选择性官能化的化学键之一，因为它们具有丰富的有机结构和对大多数化学试剂的惰性。它们在生物合成途径中的选择性氧化强调了这种反应在简化具有复杂氧化模式的分子合成方面的能力。我们报告说，铁催化剂可以在不同的天然产物环境中实现亚甲基 C-H 键氧化，
