(±)-5-[5β-(((E)-1-Octen-3-ol)-1)-2-oxabicyclo[3.3.0]octan-3-yl]-4-oxapentanoic acid (±)-(1a, b), designed as a chemically and biologically stable prostacyclin analogue, was synthesized in 15% yield overall, via the (±)-3-hydroxymethyl-5-carbethoxy-2-oxabicyclo[3.3.0]octane (4) as the key intermediate.
(±)-5-[5β-(((E)-1-癸烯-3-醇)-1)-2-氧双环[3.3.0]八烷-3-基]-4-氧戊酸(±)-(1a, b),被设计为一种在化学和生物上稳定的前列腺素类似物,最终合成的总产率为15%,以(±)-3-羟甲基-5-乙酸基-2-氧双环[3.3.0]八烷(4)作为关键中间体。
