ether moiety instead of enol-ether skeleton in PGI2. The m-phenylene PGI2 and its derivative (Beraprost) were synthesized via dihydrocyclopenta[b]benzofuran derivatives as key intermediates by ortho-selective metal-halogen exchange reaction with Grignard reagents and subsequent copper-catalyzed cyclization. The ω-side chains were introduced by stereoselective epoxide formation or Prins reaction.
我们已经公开了一类新的稳定的PGI 2类似物,5,6,7-三去甲-4,8-互米亚苯基PGI 2具有苯基醚部分代替的烯醇-醚骨架在PGI 2。所述米亚苯基PGI 2及其衍生物(贝前列素)的合成经由二氢环戊二烯并[ b由]苯并呋喃衍生物作为关键中间体邻与格氏试剂和随后的铜催化的环化-选择性金属-卤素交换反应。通过立体选择性环氧化物形成或Prins反应引入ω侧链。
