  • Total Synthesis of (-)-Silphiperfol-6-ene and (-)-Methyl Cantabradienate
    作者:Nha Huu Vo、Barry B. Snider
    DOI:10.1021/jo00097a053
    日期:1994.9
    (-)-Silphiperfol-6-ene (10) and (-)-methyl cantabradienate (11) have been prepared in seven steps from (R)-3-methyl-1-cyclopentenecarboxaldehyde in 13 and 9% overall yield, respectively. Addition of isopentenylmagnesium bromide to imine 22 afforded 65% of aldehyde 14. Oxidation provided acid 15, which was converted to ketene 20, which underwent an intramolecular [2 + 2] cycloaddition to afford cyclobutanone 13. Mn(III)-based oxidative fragmentation-cyclization of ethynyl cyclobutanol 25 provided an efficient route to the key methylenecyclopentanone 12. Addition of methyllithium and Birch reduction completed the synthesis of (-)-silphiperfol-6-ene 10. Formation of dienyl triflate 29 and palladium-catalyzed carbonylation concluded the first synthesis of (-)methyl cantabradienate (11).
    (-)-Silphiperfol-6-ene (10) 和 (-)-甲基cantabradienate (11) 已经通过从(R)-3-甲基-1-环戊烯羧酸仿开始的七步反应制备而成,总产率分别为13%和9%。将异戊烯溴化镁加成到亚胺22中,获得了65%的醛14。氧化提供了酸15,将其转化为酮烯20,随后酮烯20通过分子内[2 + 2]环加成反应生成环丁酮13。以Mn(III)为基础的氧化断裂环化反应处理乙烯基环丁醇25,为制备关键的甲基环戊酮12提供了一条高效途径。甲基锂的加成和Birch还原完成了(-)-silphiperfol-6-ene 10的合成。二烯基三氟乙酸酯29的形成以及催化的羰基化反应,标志着(-)-甲基cantabradienate (11) 的首次合成。
  • Silicon-directed nazarov cyclizations-IV
    作者:Scott E. Denmark、Karl L. Habermas、Gary A. Hite、Todd K. Jones
    DOI:10.1016/s0040-4020(01)90571-x
    日期:1986.1
    The silicon-directed Nazarov cyclization was shown to proceed with good to excellent stereoselectivity in cyclohexenyl systems bearing a variety of ring substituents. In all cases the trans family of isomers predominated, and cis ring-fused products were formed exclusively. The potential for stereocontrol by increasing the bulk of silicon substituents was limited for five-membered rings and good for
    在带有多种环取代基的环己烯基体系中,定向的Nazarov环化反应具有良好的立体选择性。在所有情况下,反式异构体都占主导地位,并且仅形成顺式环稠合产物。通过增加取代基的体积进行立体控制的潜力对于五元环是有限的,而对于六元环则是良好的。发现苯基硅烷参与环化。
  • Silicon-directed nazarov cyclizations VII
    作者:Scott E. Denmark、Russell C. Klix
    DOI:10.1016/s0040-4020(01)86655-2
    日期:1988.1
    A new modification of the silicon-directed Nazarov cyclization is described which involves the cyclization of divinyl ketones incorporating an allylsilane as the control unit. The cyclizations are extremely facile with FeCl3 or BF3·OEt2 as the Lewis acid. Four permutations of five- and six-membered ring substrates have been examined. In all cases the reactions are regio- and stereoslective. In the
    描述了对定向的Nazarov环化的一种新的改进,其中涉及以烯丙基硅烷为控制单元的二乙烯基酮的环化。用FeCl 3或BF 3 ·OEt 2作为路易斯酸,环化反应非常容易。已经检查了五元和六元环底物的四个排列。在所有情况下,反应都是区域性和立体选择性的。在6-5-6(6ba)和5-5-6(6ba)系统中,主要产品具有反跨配置。已经解决了在双键和环中引入甲基取代基的能力。
