Synthesis of new stable fluoroprostacyclins, 7-fluoro-2,4-methylene-17, 20-dimethylprostacyclins (1,2) with potent and long-lasting anti-anginal activities has been achieved. The cyclobutylene prostaglandin skeleton 10 was constructed efficiently according to three-component coupling reaction. Stereospecific fluorination of silyl ether 11 and subsequent cyclization of the fluoride 12 successfully provided
已经合成了具有有效和持久的抗心绞痛活性的新的稳定的氟代前列环素,7-氟-2,4-亚甲基-17、20-二甲基前列环素(1,2)。根据三组分偶联反应,有效地构建了环丁烯前列腺素骨架10。甲硅烷基醚11的立体定向氟化和氟化物12的随后环化成功提供了所需的7-氟-2,4-亚甲基-17,20-二甲基前列环素。
