合成路线1
该中间体在本合成路线中的序号：(XIII)The protection of the free hydroxy group of (X) with trimethylchlorosilane and hexamethyldisilazane in pyridine gives the trimethylsilyl derivative (XI), which is condensed with [3-(triphenylmethoxy)-1-octenyl](pentenyl)lithiocuprate (XII) in HMPT-ether to afford 11-deoxy-11alpha-(2-trimethyl-silyloxyethylthio)-15-triphenylmethoxy-PGE2 methyl ester (XIII). Finally, this compound is deprotected by treatment with acetic acid in THF. The lithium cuprate (XII) is prepared as follows: Hydrogen iodide addition to 3-triphenylmethoxy-1-octyne (XVII) gives 1-iodo-3-triphenylmethoxy-1-octene (XVIII), which is condensed with copper 1-pentyne (B) and butyllithium in ether.
