  • Stereoselective synthesis of carbocyclic ring systems by pinacol-terminated Prins cyclizations
    作者:Timothy C Gahman、Larry E Overman
    DOI:10.1016/s0040-4020(02)00658-0
    日期:2002.8
    Studies that expand the scope of the Prins-pinacol synthesis of carbocyclic ring systems are described. The construction of cyclopentacyclooctanones by ring-enlarging cyclopentane annulations of cycloheptanone precursors is broadly examined as is the synthesis of related bicyclic ketones containing larger rings. Prins-pinacol reactions of acyclic alkenyl acetals were examined to gain insight into intrinsic
    描述了扩大碳环系统的Prins-频哪醇合成范围的研究。广泛地研究了通过环庚酮前体的环戊烷环的扩环来构建环戊环辛酮,以及相关的包含更大环的双环酮的合成。研究了无环烯基缩醛的Prins-频哪醇反应,以了解环扩大的环戊烷环化过程中固有的立体化学控制元素。本报告中描述的碳环结构的结果通过我们最近开发的用于描述四氢呋喃的Prins-频哪醇结构的机理分析得到了合理化。

    The synthesis of a variety of tungsten alkyl complexes of the type [N3N]WR ([N3N]3- = [(Me3SiNCH2CH2)3N]3-; R = Me, Et, Bu, CH2Ph, CH2SiMe3, CH2CMe3, cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cyclopentenyl) was attempted by alkylation of [N3N]WCl complexes. Only the methyl, phenyl, and cyclopentenyl complexes could be isolated. The susceptibility of the [N3N]WR complexes is similar to that

  • Addition of 2,3-dihydro-5-furanyllithium to diisopropyl squarate as a means for the rapid generation of structurally complex oxygen-containing tetraquinane networks
    作者:Leo A. Paquette、Tina M. Morwick、Joanna T. Negri、Robin D. Rogers

    日期:1996.2
    The ability of 2,3-dihydro-5-furanyllithium (11) to trigger a reaction cascade when added to diisopropyl squarate (6) has been examined. Of particular concern were those experiments in which greater than 2 equiv of 11 were added to 6, as well when 1 equiv of 11 was added prior to or after an equiv of cyclopentenyllithium. The results shed light directly on such issues as whether the second vinyl anion
    当2,3-二氢-5-呋喃基锂(11)添加到二异丙基二甲基碳酸酯(6)中时,其触发反应级联的能力已得到检验。特别令人关注的是其中大于2当量的那些实验11加入到6,以及当1当量的11在等当量的环戊烯基锂之前或之后加入α-烯烃。结果直接阐明了诸如第二乙烯基阴离子相对于第一乙烯基阴离子是添加顺式还是反式以及键合是以1,2还是1,4方式发生的问题。在不对称的案例研究中还揭示了1,3,5-环辛三烯中间体的质子化是与相邻质子同位还是反位,以及在“常规”位点或氧取代的烯醇酸酯位点实现的程度。考虑到一个事实,即从非手性结构单元一步一步直接制备出包含五个立体异构中心的杂环四喹烷,可以合理地将这项工作中描述的转化归类为“动力反应”。
  • Asymmetric Synthesis of 3,4-Annulated Cyclopentenones from Cycloalkenyl Ketones and Vinyl Carbamates by Diastereoselective Carbonyl Addition/Conrotatory 4π Ring Closure
    作者:Dieter Hoppe、Michael Siemer、Roland Fröhlich
    DOI:10.1055/s-2008-1067150
    日期:2008.7
    1-Lithiated O-vinyl carbamates add with high induced diastereoselectivity onto enantiomerically pure cycloalk-1-enyl (1-dibenzylamino)alkyl ketones. Subsequent O-carbamoyl migration, followed by a torquoselective, antarafacial 4π ring closure, leads to homochiral 2-substituted bicyclo[n.3.0]alk-1-ene-2-ones.
