合成路线1
该中间体在本合成路线中的序号：(I)The condensation of 2-[3-(trifluoromethyl)phenoxy]acetyl chloride (I) with methylphosphonic acid dimethyl ester (II) by means of BuLi in THF gives 2-oxo-3-[3-(trifluoromethyl)phenoxy]propylphosphonic acid dimethyl ester (III), which is condensed with the known bicyclic aldehyde (IV) by means of BuLi in dimethoxyethane, yielding the unsaturated ketone (V). The reduction of (V) with zinc borohydride in dimethoxyethane affords the unsaturated alcohol (VI), which is treated with K2CO3 to give a diastereomeric mixture of unsaturated diols, resolved by chromatography to yield the chiral unsaturated diol (VII). The protection of (VII) with dihydropyran and TsOH in dichloromethane provides the bis(tetrahydropyranyl) ether (VIII), which by reduction of the lactone ring with diisobutylaluminum hydride in THF gives the lactol (IX). The condensation of (IX) with the phosphonium bromide (X) by means of NaH in DMSO yields the prostenoic acid (XI), which is esterified with isopropyl iodide and 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) in acetone to afford the corresponding isopropyl ester (XII). Finally, this compound is deprotected with acetic acid in hot THF/water.
