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
