Convergent synthesis of an antitumor protective agent, ascofuranone, was accomplished by (1) preparation of the terpenoid side chain having a furanone moiety, (2) coupling the side chain with a protected phenol derivative, and (3) deprotection to regenerate the hydroxyl groups. This strategy was successfully applied to the synthesis of oxidized and cyclized analogs of ascofuranone. Some of the ascofuranone
通过 (1) 制备具有呋喃酮部分的萜类侧链,(2) 将侧链与受保护的苯酚衍生物偶联,以及 (3) 脱保护以再生羟基,从而实现了抗肿瘤保护剂 ascofuranone 的聚合合成. 该策略已成功应用于合成呋喃酮的氧化和环化类似物。发现一些呋喃酮衍生物可抑制 P388 白血病细胞的生长。
