Syntheses of several stable PGI2 analogs substituted by an electron-withdrawing substituent at C-5 or C-7 are described. Reaction of PGI2 methyl ester () with benzenesulfenyl chloride gave (5E)-5-phenylthio-PGI2 () or (5 R)-5-phenylthio-Δ6-PGI1 () according to the reaction condition employed. Allyl sulfide was transformed into (7 S )-7-hydroxy-PGI2 () and (7 S )-7-acetoxy-PGI2 () via stereocontrolled
描述了在C-5或C-7被吸电子取代基取代的几种稳定的PGI 2类似物的合成。PGI的反应2甲酯()与氯化benzenesulfenyl得到(5 ë)-5-苯基硫代PGI 2()或(5 - [R)-5-苯硫基Δ 6 -PGI 1(根据所采用的反应条件)。通过立体控制的亚砜亚硫酸盐重排和乙醇将烯丙基硫醚转化为(7 S)-7-羟基-PGI 2()和(7 S)-7-乙酰氧基-PGI 2()将其进一步转化为(7S)-7-氟-PG12 (2)。发现这些PGI 2类似物比PGI 2稳定得多。
