以
甲醇 为溶剂,
以gave an Rf value for ω-homo-PGE1 of 0.34的产率得到7-[(1R,2R,3R)-3-Hydroxy-2-((E)-(S)-3-hydroxy-non-1-enyl)-5-oxo-cyclopentyl]-heptanoic acid
The present invention provides a method for producing a compound represented by Formula (1a), (1b), or (1c), comprising a step of reducing a compound represented by Formula (3) in the presence of a metal complex represented by Formula (5), an inorganic base, and a solvent under a hydrogen atmosphere to obtain a compound represented by Formula (4). In the formula, Ar
1
is an aryl group, each Are is independently a phenyl group or the like, W is a biphenyl group or the like, Z is an ethylene group that is substituted with a phenyl group or the like, and L is a chlorine atom or if Z has a phenyl group or a C
1-3
alkoxyphenyl group, L is one of carbon atoms constituting the phenyl group or the C
1-3
alkoxyphenyl group.
.omega.-Nor and .omega.-homo prostaglandins E having blood platelet aggregation-inhibiting activity are prepared by enzymatic synthesis fron nonadeca- and henicosa- -8c, 11c,14c-trienoic acids.
