  Borenium Ion Catalyzed Hydroboration of Alkenes with N-Heterocyclic Carbene-Boranes

  摘要：

  Treatment of alkenes such as 3-hexene, 3-octene, and 1-cyclohexyl-1-butene with the N-heterocyclic carbene (NHC)-derived borane 2 and catalytic HNTf2 (Tf = trifluoromethanesulfonyl (CF3SO2)) effects hydroboration at room temperature. With 3-hexene, surprisingly facile migration of the boron atom from C(3) of the hexyl group to C(2) was observed over a time scale of minutes to hours. Oxidative workup gave a mixture of alcohols containing 2-hexanol as the major product. A similar preference for the C(2) alcohol was observed after oxidative workup of the 3-octene and 1-cyclohexyl-1-butene hydroborations. NHC-borenium cations (or functional equivalents) are postulated as the species that accomplish the hydroborations, and the C(2) selective migrations are attributed to the four center interconversion of borenium cations with cationic NHC-borane-olefin pi-complexes.

  activated substrates to achieve appreciable conversion without side product formation. Motivated by stereoinvertive epoxide carbonylation reactions, we developed a two-step epoxidation/deoxygenation process that results in overall inversion of alkene stereochemistry. Unlike most deoxygenation systems, carbon monoxide was used as the terminal reductant, preventing difficult postreaction separations, given

  促进烯烃立体化学反转的反应是现代有机合成领域罕见的、广受欢迎的转化。尽管存在许多异构化反应，但大多数方法需要特定的、高度活化的底物来实现可观的转化，而不会形成副产物。在立体转化环氧化物羰基化反应的推动下，我们开发了一个两步环氧化/脱氧过程，导致烯烃立体化学的整体转化。与大多数脱氧系统不同，考虑到生成的二氧化碳副产物的气态性质，一氧化碳被用作终端还原剂，防止了困难的反应后分离。各种烷基取代的顺式和反式环氧化物可以分别还原为反式和顺式烯烃，立体定向性 > 99:1，产率高达 95%，

Using the optimal reaction conditions, good to high yields (53–76%) of both γ- and δ-lactam spirocycles were obtained. The synthetic utility of the spirolactams

  日期：2007.6

  CuCN catalyzed alkyl-allyl coupling under magnesium-Barbier conditions occurs regioselectively and affords predominantly the gamma-products in good to high yields. This one-pot CuCN catalyzed reaction utilising Mg, an alkyl halide and an allylic substrate in THF at room temperature provides an easy alternative to the classical CuCN catalyzed gamma-allylation of alkyl Grignard reagents.
