  • Indole-Diterpene Synthetic Studies: Total Synthesis of (−)-21-Isopentenylpaxilline
    作者:Amos B. Smith、Haifeng Cui
    DOI:10.1002/hlca.200390328
    日期:2003.12
    An efficient, stereocontrolled total synthesis of the complex indole-diterpene alkaloid (−)-21-isopentenylpaxilline (1) has been achieved. Key elements of the synthesis include the stereocontrolled construction of the advanced eastern hemisphere (−)-68, involving a highly efficient union of the eastern and western fragments (−)-68 and 5 exploiting our 2-substituted indole synthesis, application of

  • An end-game strategy for construction of the G-H-I rings of penitrem D, A tremorgenic indole alkaloid
    作者:Amos B. Smith、Mitsuaki Ohta、William M. Clark、James W. Leahy
    DOI:10.1016/s0040-4039(00)93371-9
    日期:1993.5
    synthetic approach to the G-H-I ring system of penitrem D has been developed in a model study. To generate the requisite carbon framework, the Stork protocol was utilized for coupling of a scalemic metalloenamine with an epoxide derived from D-glyceraldehyde. Pyran ring formation was then effected via BF3·OEt2-promoted cyclization of a δ-hydroxy allylic acetate.
    在模型研究中,已开发出一种综合的方法来合成Penitrem D的GHI环系统。为了生成必要的碳骨架,利用Stork方案将鳞状金属烯胺与衍生自D-甘油醛的环氧化物偶联。然后通过BF 3 ·OEt 2促进的δ-羟基烯丙基乙酸酯的环化作用实现吡喃环的形成。

  • Synthesis of Optically Active β,γ-Unsaturated α-Amino Acids and of α,β-Unsaturated γ-Amino Acids. SN2- vs. SN2’-Dichotomy of the Mitsunobu Amination of Allylic Alcohols
    作者:Johann Mulzer、Günther Funk
    DOI:10.1055/s-1995-3847
    日期:1995.1
    Novel and efficient syntheses (6-9 steps, overall yields 10-30%) are described for optically pure β,γ-unsaturated α-amino acids and α,β-unsaturated γ-amino acids, starting from (R)-isopropylidene glyceraldehyde and ethyl (S)-lactate, respectively. The key step is the Mitsunobu reaction of chiral secondary allylic alcohols with phthalimide as the nucleophile, where α,γ allylic transpositions are observed for the first time. The structure-α,γ-ratio-relationship is studied and also the stereochemistry of the allylic transposition. The α-substitution proceeds via clean SN2 inversion, whereas the γ-substitution corresponds to an (E)-anti attack of the nucleophilic with varying stereoselectivities.
    本文描述了从(R)-异丙叉甘油醛和乙基(S)-乳酸分别合成光学纯的β,γ-不饱和α-氨基酸和α,β-不饱和γ-氨基酸的新颖且高效的方法(总步骤为6-9步,总收率为10-30%)。关键步骤是手性仲烯丙醇与酞酰亚胺作为亲核试剂的 Mitsunobu 反应,首次观察到α,γ 烯丙基重排现象。研究了结构-α,γ 比例关系以及烯丙基重排的立体化学。α-取代过程通过干净的 SN2 反转进行,而γ-取代对应于亲核试剂的(E)-反向攻击,具有不同的立体选择性。
