    Unified flexible total synthesis of chlorofusin and artificial Click mimics as antagonists against p53–HDM2 interactions
    摘要:
    A practical HPLC-free total synthesis of chlorofusin has been successfully accomplished in this work. The new synthesis showed great flexibility and convenience in generating artificial natural product-like mimics through Click chemistry, and enabled us to further investigate the biological importance of the chromophore and the spiro-aminal functionality of the natural product. The entire skeleton is believed to be essential for satisfactory biological activities of both natural chlorofusin and unnatural mimics. Two artificial Click hybrids were found to exhibit improved inhibitory activity against p53-HDM2 bindings over the natural product. (C) 2014 Elsevier Ltd. All rights reserved.

    spectroscopic properties for these eight compounds and those of simpler models with that reported for the natural product allowed the full assignment of the (4R,8S,9R)-stereochemistry of the chlorofusin chromophore. The natural, but stereochemically reassigned, diastereomer of the dipeptide conjugate was incorporated in a convergent total synthesis of chlorofusin confirming the stereochemical reassignment

  • Bromoetherification-based strategy towards the spirocyclic chromophore of chlorofusin
    作者:Wan-Guo Wei、Wen-Jian Qian、Yong-Xia Zhang、Zhu-Jun Yao
    DOI:10.1016/j.tetlet.2006.04.062
    日期:2006.6
    A short and direct route to the racemic model chromophore of the potent p53-MDM2 antagonist, chlorofusin, is presented. The spirocyclic chromophores were successfully constructed in high yields by an NBS-mediated intramolecular haloetherification. Ring expansion was observed in the subsequent reaction of the bromides with silver nitrate in refluxing acetone and water. Conversion of the bromides to the desired ketones was finally achieved by NMO oxidation. All four possible isomeric chromophores were finally synthesized and unambiguously characterized by X-ray crystallography studies. (c) 2006 Elsevier Ltd. All rights reserved.
