  • Formal Synthesis of (−)-Cephalotaxine Based on a Tandem Hydroamination/Semipinacol Rearrangement Reaction
    作者:Qing-Wei Zhang、Kai Xiang、Yong-Qiang Tu、Shu-Yu Zhang、Xiao-Ming Zhang、Yu-Ming Zhao、Tian-Cai Zhang

    日期:2012.5
    Catalytic asymmetric formal synthesis of (−)‐cephalotaxine has been accomplished based on an efficient tandem intramolecular hydroamination/asymmetric semipinacol rearrangement reaction catalyzed by chiral silver phosphate. During the course of the study it was observed that an advanced intermediate could be obtained in enantiopure form by enantiomer separation on silica gel.

  • Convergency and Divergency as Strategic Elements in Total Synthesis:  The Total Synthesis of (−)-Drupacine and the Formal Total Synthesis of (±)-Cephalotaxine, (−)-Cephalotaxine, and (+)-Cephalotaxine
    作者:Qi Liu、Eric M. Ferreira、Brian M. Stoltz
    DOI:10.1021/jo0710883
    日期:2007.9.1
    A concise route toward the syntheses of ()-drupacine and (+)- and ()-cephalotaxine has been developed. The syntheses rely on Pd(II)-catalyzed aerobic oxidative heterocyclization chemistry, which was employed to rapidly construct an important spirocyclic amine intermediate. A dynamic β-elimination/conjugate addition process was strategically applied to complete the first asymmetric total synthesis

    日期:1999.11.1
    Cephalotaxine (1), the major alkaloid isolated from Cephalotaxus species, has attracted considerable attention due to the promising antitumor activity of several of its derivatives and its unique structural features. Herein we describe a highly efficient enantioselective synthesis of 1 employing two successive Pd-catalyzed transformations starting from 25 to give the pentacyclic product 6. The controlling
    Cephalotaxine (1) 是从 Cephalotaxus 物种中分离出来的主要生物碱,由于其几种衍生物的有希望的抗肿瘤活性及其独特的结构特征而引起了相当大的关注。在本文中,我们描述了 1 的高效对映选择性合成,采用两个连续的 Pd 催化转化,从 25 开始得到五环产物 6。 25 中的控制立体中心是通过对映选择性还原烯酮 16 引入的。

    An enantioselective formal synthesis of the alkaloid (-)-cephalotaxine has been completed, using an alkylidene carbene 1,5-CH insertion reaction as a key step to construct the spiro[4.4]azanonane core D/E-ring system. A Heck-type cyclization was used to close the tetrahydroazepine C-ring and a selective epoxidation-rearrangement sequence was used to elaborate the E-ring.

    作者:Monica G. Gonçalves-Martin、Sarunas Zigmantas、Philippe Renaud
    DOI:10.1002/hlca.201200486
    日期:2012.12
    A formal synthesis of ()‐cephalotaxine (1) by means of a highly stereoselective radical carboazidation process is reported. The synthesis begins with the protected (S)‐cyclopent‐2‐en‐1‐ol derivative 10 and uses the concept of self‐reproduction of a stereogenic center (Schemes 5 and 6). For this purpose, the double bond adjacent to the initial chiral center in 10 is converted into an acetonide after
    据报道,通过高度立体选择性的自由基碳叠氮化过程可以正式合成(-)-头孢他辛(1)。合成从受保护的(S)-环戊-2-烯-1-醇衍生物10开始,并使用立体中心的自我复制概念(方案5和6)。为此目的,在立体选择性二羟基化之后,将与10中的初始手性中心相邻的双键转变成乙炔化物。最初的醇官能团用于构建适合8 → 7碳叠氮化过程(方案7)的环外亚甲基。最后,将受保护的二醇部分转化回烯烃(14 → 15 → 6)和用于形成环的通过乙一个的Heck反应(6 →( - ) - 16 ;方案8)。
