  Palladium-catalyzed cyclizations of polyenynes. A palladium zipper

  摘要：

  The cycloisomerization of polyenynes with a catalyst derived from Pd(0), acetic acid, and a ligand to polycycles depends upon the juxtaposition of unsaturation. The process involves the stages of initiation (by addition of Pd-H to an acetylene), propagation (by intramolecular carbopalladation), and termination (by beta-hydrogen elimination). With 2-homopropargylated 1,5- and 1,6-dienes, monocyclizations via 5-exo and 6-endo modes dominate with the ratio dependent upon ligand. The 5-exo mode is favored by tri-o-tolylphosphine, whereas triphenylstibine favors the 6-endo mode. On the other hand, a 3-homoallyl-3-homopropargylcyclopentene undergoes smooth bicyclization even when triphenylphosphine is used as ligand. Combining Pd(0)-catalyzed allylic alkylation to make the substrates with Pd(0)-catalyzed cycloisomerization simplifies triquinane and azatriquinane synthesis. A2-allyl-2-homopropargyl-1-methylenecycloalkane array cycloisomerizes to [4.3.3]propellanes and [3.3.3]propellanes. Methallyl alcohol serves as a basic building block to construct acyclic substrates for construction of spirocycles. Both terminal and internal acetylenes serve as suitable initiators provided the proper ligand is employed. With a terminal acetylene as initiator, triphenylphosphine proves satisfactory, but an internal acetylene requires triphenylstibine. High diastereoselectivity may accompany formation of the spirocycle. Increasing the number of double bonds increases the number of rings formed. Substrates bearing 3, 4, 5, 6, and 7 double bonds generate polyspiranes consisting of 3, 4, 5, 6, and 7 rings. The regio- and diastereoselectivity may be understood on the basis of a conformational analysis of the reactive intermediate. This atom economical approach for construction of polycycles can be considered as the equivalent of a palladium zipper in which the pi orbitals are the teeth and the palladium complex is the tab. Closing the zipper stitches the pi bonds into sigma bonds with creation of the polycycles.

  (-)-Phaeocaulisin A 的不对称全合成

  摘要：

  姜黄（姜和姜黄家族）的治疗特性在传统医学中早已为人所知。然而，直到最近才有从姜黄中提取的愈创木脂类倍半萜已提交生物测试，并强调其增强的生物活性。在这些化合物中，phaeocaulisin A 显示出显着的抗炎和抗癌活性，这似乎与嵌入其四环框架中的独特桥接缩醛部分有关。由于 phaeocaulisin A 的有希望的生物学特征以及缺乏合成路线的提示，我们已经在 17 个步骤中实现了 phaeocaulisin A 的第一个对映选择性全合成，总产率为 2%。我们的路线设计建立在鉴定富含对映体的内酯中间体的基础上，该中间体采用酮部分和共轭烯烃系统进行定制。利用原型单电子转移 (SET) 还原剂二碘化钐 (SmI) 实现的 umpolung 羰基-烯烃偶联反应性2), the lactone intermediate was submitted to two sequential SmI2-mediated

  The rapid synthesis of bicyclo[m.n.1]alkanone cores possessing quaternary carbon centers adjacent to a bridged ketone represents a significant synthetic challenge. This type of architectural feature is embedded in various complex biologically active compounds such as hyperforin and garsubellin A. Herein, we report a highly diastereoselective one-pot Diels–Alder reaction/Au(I)-catalyzed carbocyclization to generate bicyclo[3.3.1]alkanones in yields ranging from 48–93%.
