  • Total Synthesis of (−)-Apratoxin A, 34-Epimer, and Its Oxazoline Analogue
    作者:Yoshitaka Numajiri、Takashi Takahashi、Takayuki Doi
    DOI:10.1002/asia.200800365
    日期:2009.1.5
    convergent total synthesis of the highly cytotoxic marine natural product apratoxin A is accomplished by an 18‐step linear sequence. The high sensitivity of the thiazoline, bearing an adjacent β‐hydroxyl group at the C35‐position, results in the assembly process requiring the inclusion of appropriate protecting groups and the careful optimization of all individual transformations. In the synthesis of 3,7‐dihydroxy‐2
    通过18个步骤的线性序列即可完成高度收敛的高度细胞毒性海洋天然产物Apratoxin A的简明和收敛性合成。噻唑啉具有很高的敏感性,在C35位带有一个相邻的β-羟基,导致组装过程中需要包括适当的保护基并仔细优化所有单独的转化。在3,7-二羟基-2-5,8,8-四甲基壬酸(Dtena)的合成中,三个试剂控制的不对称反应使我们能够在二羟基化脂肪酸部分引入四个手性碳中心。成功地证明了受阻酯的形成和空间不利的N-甲基酰胺键。Tf 2 O和Ph合成了Apratoxin A中的噻唑啉3 PO介导的脱水环化作用,在N-甲基异亮氨酸和脯氨酸残基之间实现了最终的大环化。此外,也已经以类似的方式对恶唑啉类似物和Apratoxin A的C34差向异构体进行了详细的阐述。该合成途径将使得能够组装在Dtena的立体中心及其氨基酸方面不同的其他类似物。
  • Lewis acid catalyzed stereoselective hydrosilylation of ketones under the control of σ–π chelation
    作者:Naoki Asao、Takeshi Ohishi、Kenichiro Sato、Yoshinori Yamamoto

    Felkin–Anh model. On the other hand, the unusual syn-selectivity in the latter cases can be accounted for by the σ–π chelation by R3Si+, in which both the lone pair (σ) of the carbonyl group and the π-electrons of the alkyne coordinate to the silylium ion. The σ–π chelation control was also effective for the 1,3-asymmetric induction.
    在催化量的B(C 6 F 5)3存在下,将2-甲基-1-苯基-戊烷-1-酮与Et 3 SiH进行硅氢加成反应,得到的反产物略高于同产物(syn / anti = 1:1.5)。相反,在β位上带有乙炔基的2-甲基-1-苯基-戊-4-yn-1-one的反应中,立体选择性地获得了顺式产物(syn / anti= 7∶1)。所述顺式-selectivities也在B观察到的(C 6 ˚F 5)3-α-甲基-β-炔基芳基酮和α-甲基-β-炔基烷基酮等其他相关酮的催化反应。在前一种情况下观察到的适度的抗选择性可以用普通的Felkin–Anh模型来解释。另一方面,R 3 Si +的σ-π螯合可解释后一种情况下异常的顺选择性,其中羰基的孤对(σ)和π的电子炔与硅离子配位。σ-π螯合控制对1,3-不对称诱导也有效。
  • Total Synthesis of Apratoxin A

    DOI:10.1021/ja036050w
    日期:2003.7.1
    Apratoxin A, a cyclodepsipeptide isolated from cyanobacterial Lyngbya spp, has been synthesized. The total synthesis features stereocontrolled access to the novel polyketide and the late-stage installation of the sensitive 2,4-disubstituted thiazoline moiety using an intramolecular Staudinger reduction/aza-Wittig process.

  • Improved Total Synthesis and Biological Evaluation of Potent Apratoxin S4 Based Anticancer Agents with Differential Stability and Further Enhanced Activity
    作者:Qi-Yin Chen、Yanxia Liu、Weijing Cai、Hendrik Luesch
    DOI:10.1021/jm4019965
    日期:2014.4.10
    Apratoxins are cytotoxic natural products originally isolated from marine cyanobacteria that act by preventing cotranslational translocation early in the secretory pathway to downregulate receptor levels and inhibit growth factor secretion, leading to potent antiproliferative activity. Through rational design and total synthesis of an apratoxin A/ E hybrid, apratoxin S4 (1a), we have previously improved the antitumor activity and tolerability in vivo. Compound la and newly designed analogues apratoxins S7-S9 (1b-d), with various degrees of methylation at C34 (1b,c) or epimeric configuration at C30 (1d), were efficiently synthesized utilizing improved procedures. Optimizations have been applied to the synthesis of key intermediate aldehyde 7 and further include the application of Leighton's silanes and modifications of Kelly's methods to induce thiazoline ring formation in other crucial steps of the apratoxin synthesis. Apratoxin S9 (1d) exhibited increased activity with subnanomolar potency. Apratoxin S8 (lc) lacks the propensity to be deactivated by dehydration and showed efficacy in a human HCT116 xenograft mouse model.
