    Stereoselective acetalization of 1,3-alkanediols by l-menthone: application to the resolution of racemic 1,3-alkanediols and to the determination of the absolute configuration of enantiomeric 1,3-alkanediols
    摘要:
    A general and reliable method for the resolution of racemic 1,3-alkanediols, which involves their conversion into diastereomeric spiroacetals derived from l-menthone, is described. Thus, the reaction of the bis-O-trimethylsilyl derivatives of racemic 1,3-alkanediols with l-menthone in the presence of a catalytic amount of trimethylsilyl trifluoromethanesulfonate affords the diastereomeric spiroacetals 3 and 4. The two can be readily separated by silica gel column chromatography. Hydrolysis of each diastereomer under acidic conditions liberates the corresponding enantiomerically pure diol. An empirically derived correlation of configuration and H-1 NMR chemical shifts for spiroacetals 3 and 4 has been developed which is rationalized based on long-range effects due to the magnetic anisotropy inherent to the menthane ring in a rigid spiroacetal conformation. The method described here should be widely applicable to the determination of the absolute configuration of various 1,3-alkanediols.

  • Asymmetric Total Synthesis of the Indole Diterpene Alkaloid Paspaline
    作者:Robert J. Sharpe、Jeffrey S. Johnson

    日期:2015.10.2
    An enantioselective synthesis of the indole diterpenoid natural product paspaline is disclosed. Critical to this approach was the implementation of stereoselective desymmetrization reactions to assemble key stereocenters of the molecule. The design and execution of these tactics are described in detail, and a thorough analysis of observed outcomes is presented, ultimately providing the title compound

    A novel diazo-cascade approach has been developed for the synthesis of nine-membered oxacycles utilizing readily accessible β-hydroxy vinyl ketones and vinyl diazo esters. The Rh(II)-catalyzed cascade reaction begins with carbene O–H insertion followed by an intramolecular aldol cyclization to provide a substituted tetrahydrofuran intermediate that undergoes an oxy-Cope rearrangement to provide functionalized

    achieved. The basis of this result was a careful substrate design making use of a syn-pentane interaction as the decisive stereochemical control element. Confirmation of this working hypothesis came from conformational analysis studies on alkenic substrate 16 employing 2D NOESY experiments in solution and MACROMODEL/MM3 calculations. This stereoselective, transition metal-catalyzed, C-C bond-forming
    已经实现了具有优异水平的无环立体控制的2-亚丙基取代的1,3-二恶烷16、17和26的抗选择性加氢甲酰基化。该结果的基础是使用正戊烷相互作用作为决定性立体化学控制元素的仔细的底物设计。对该工作假设的证实来自对烯属底物16的构象分析研究,该研究在溶液中进行了2D NOESY实验,并进行了MACROMODEL / MM3计算。这种立体选择性的,过渡金属催化的CC键形成反应可以作为构建全反和同反立体三单元构建基20、21和31的关键步骤,应该非常适合于目标定向聚丙烯酸酯的合成。
