    Enantioselective synthesis of the C-14 to C-5 cyclopentane segment of jatrophane diterpenes
    摘要:
    The enantioselective synthesis of the C-14 to C-5 cyclopentane segment of jatrophane diterpenes is reported. An Evans aldol addition, a Horner-Wadsworth-Emmons olefination and a thermal intramolecular carbonylene reaction of an alpha-keto ester served as key C/C-connecting transformations.

  • Palladium-Catalyzed γ-Selective and Stereospecific Allyl−Aryl Coupling between Acyclic Allylic Esters and Arylboronic Acids

    Reactions between acyclic (E)-allylic acetates and arylboronic acids in the presence of a palladium catalyst prepared from Pd(OAc)(2), phenanthroline (or bipyridine), and AgSbF(6) (1:1.2:1) proceeded with excellent gamma-selectivity to afford allyl-aryl coupling products with E-configuration. The reactions of alpha-chiral allylic acetates took place with excellent alpha-to-gamma chirality transfer

    germanium(II) iodide with potassium metal, was found to promote the Reformatsky reaction effectively under mild conditions. In the presence of activated germanium metal, the reactions of alpha-bromo ketones 2a and 2b and alpha-bromo imides 2e and 2f with benzaldehyde (1a) proceeded smoothly to give the corresponding beta-hydroxy carbonyl compounds 3a, 3b, 3e and 3f, respectively, in good yields and with
    人们发现,在温和的条件下,通过用钾金属还原碘化锗(II)制备的活化锗金属可有效促进Reformatsky反应。在活化锗金属的存在下,α-溴代酮2a和2b以及α-溴代酰亚胺2e和2f与苯甲醛(1a)的反应顺利进行,得到相应的β-羟基羰基化合物3a,3b,3e和3f,分别具有良好的收率和良好的非对映选择性。还研究了对映体纯的恶唑烷酮衍生物2g-j与各种醛1a-d的活化的锗金属促进的不对称Reformatsky反应;当(1S,2R)-2-氨基-1,2-二苯乙醇衍生的2j被用作Reformatsky供体时,获得了最高的非对映选择性。极好的非对映选择性可以用齐默曼-特拉克斯勒模型中在醛和烯醇酸酯之间形成的椅子状六元过渡态来解释。Reformatsky加合物的一次重结晶,然后水解和随后的酯化反应,产生对映体纯的3-羟基-2-甲基链烷酸甲酯10j-m,几乎定量回收了对映体纯的2-恶唑烷酮14。
  • Asymmetric aldol reactions: a novel model for switching between chelation- and non-chelation-controlled aldol reactions
    作者:Tu Hsin Yan、Chang Wei Tan、Hui Chun Lee、Hua Chi Lo、Tzung Yu Huang
    DOI:10.1021/ja00060a010
    日期:1993.4
    A new camphor-based N-propionyloxazolidinethione provides remarkable levels of asymmetric induction for both chelation-and non-chelation-controlled aldol processes. While the aldol condensation of the derived di-n-butylboryl enolate with various aldehydes affords the 'Evans'' syn aldol with excellent diastereoselectivity, the chlorotitanium enolate gives the ''non-Evans' syn aldol expected from chelation control. Most noteworthy is the observation that the sense of facial selectivity from the chlorotitanium enolate of propionyloxazolidinethione is opposite to that obtained from propionyloxazolidinone. This important finding illustrates the importance of increased chelating potential of the enolate ligand, ring thiocarbonyl, in maximizing the aldol pi-facial discrimination. Final nondestructive chiral auxiliary removal via hydroperoxide-assisted hydrolysis and subsequent esterification provides enantiomerically pure methoxy-carbonyl aldols.
  • Synthetic Studies toward Jatrophane Diterpenes from <i>Euphorbia characias</i>. Enantioselective Synthesis of (−)-15-<i>O</i>-Acetyl-3-<i>O</i>-propionyl-17-norcharaciol
    作者:Hannes Helmboldt、Martin Hiersemann
    DOI:10.1021/jo802581g
    日期:2009.2.20
    The enantioselective synthesis of (+)-17-norcharaciol is described. An uncatalyzed intramolecular carbonyl-ene reaction and a ring-closing metathesis were used as key C/C-connecting transformations to assemble the trans-bicyclo[10.3.0]pentadecane norditerpenoid core. We also report the evolution of our synthetic strategy toward the fully substituted characiol skeleton and the experiences from this venture.
