  • Stereoselective Synthesis of (−)-Cephalotaxine and C-7 Alkylated Analogues
    作者:Loïc Planas、Joëlle Pérard-Viret、Jacques Royer
    DOI:10.1021/jo049884l
    日期:2004.4.1
    A total asymmetric synthesis of (−)-cephalotaxine is reported. The chemistry of α,β-unsaturated γ-lactams was used to access the 1-azaspiro[4.4]nonane skeleton in enantiomerically pure form via a stereocontrolled semipinacolic rearrangement of an α-hydroxyiminium ion. This spiro compound was transformed into (−)-cephalotaxine without any racemization or epimerization by following the racemic synthesis
    报道了(-)-头孢他辛的总不对称合成。使用α,β-不饱和γ-内酰胺的化学反应,通过对映体纯的α-羟基亚胺鎓离子的半pinacolic重排,以对映体纯净的形式进入1-azaspiro [4.4]壬烷骨架。通过遵循Kuehne报告的外消旋合成,可将该螺化合物无任何消旋化或差向异构化地转化为(-)-头孢他辛。因此,我们在16个步骤的序列中以98.7%ee的总合成了(-)-头孢他辛,总产率为9.8%。该合成方法适合于某些烷基化类似物的获得。
  • Asymmetric Formal Synthesis of (−)-Cephalotaxine via Palladium-Catalyzed Enantioselective Tsuji Allylation

    DOI:10.1021/acs.orglett.7b04008
    日期:2018.2.16
    Asymmetric synthesis of the pentacyclic alkaloid ()-cephalotaxine was accomplished via palladium-catalyzed enantioselective Tsuji allylation for construction of the aza-containing tetrasubstituted stereogenic center (95% yield, 93% ee). The allyl enol carbonate precursor was prepared from Hanaoka’s ketone intermediate, which was formed by a novel formic acid promoted ring-expansion reaction.
    五环生物碱(-)-头孢他辛的不对称合成是通过钯催化的对映选择性Tsuji烯丙基化反应完成的,用于构建含氮杂的四取代立体异构中心(产率为95%,ee为93%)。由花冈的酮中间体制得烯丙基碳酸酯烯丙酸酯前体,后者是由新型的甲酸促进的环扩环反应形成的。
  • A total synthesis of (.+-.)-cephalotaxinamide.

    (±)-Cephalotaxinamide (6) was synthesized from pyroglutamic acid via the pyrrolobenzazepine (4) through the Claisen rearrangement, the Wacker oxidation, aldol condensation, and hydroxylation with iodosobenzene.
    (±)-Cephalotaxinamide (6)是由焦谷氨酸通过吡咯并氮杂卓(4)经克莱森重排、瓦克氧化、醛醇缩合和碘苯羟基化反应合成的。
