due to its strong inhibitory effect on several human tumors including Yoshida sarcoma, Sarcoma-180 and Hela carcinoma. But its total synthesis presents great difficulties due to the fact that sarkomycin and its derivatives with five membered ring are less chemically stable, highly sensitive to both bases and acids, and undergo dimerization and polymeri-zation easily. Owing to the increasing appearance
由于其对包括吉田肉瘤、肉瘤180和Hela癌在内的几种人类肿瘤具有很强的抑制作用。但其全合成存在很大的困难,因为sarkomycin及其五元环衍生物化学稳定性较差,对碱和酸均高度敏感,易发生二聚和聚合反应。由于在大量天然产物中越来越多地出现环戊烷环,特别是那些具有生物学重要性的产物,最近人们努力开发新的合成方法来构建
