The condensation of dimethyl 3-oxoundecane-1,11-dioate with styrylglyoxal affords 14-phenyl-9,12-dioxo-11-hydroxytetradec-13-enoic acid, which is cyclized to afford 3-hydroxy-5-oxo-2-styrylcyclopent-1-eneheptanoic acid. Hydroxylation of the styryl double bond affords the corresponding 2-(.alpha.,.beta.-dihydroxyphenethyl) derivative. Resolution of the racemic 2-styryl-3-hydroxy compounds with either (-) or (+)-O-methylmandelyl chloride yields the optically active isomers which are separated chromatographically. The instant compounds are useful as anti-microbial, anti-fungal and hypotensive agents, as prostaglandin (PGE.sub.2) antagonists and also as intermediates to prostanoic acid derivatives and their optically active isomers which exhibit anti-microbial, pepsin-inhibitory, hypotensive and smooth muscle-contracting properties.
二甲基3-氧代十一酸-1,11-二酯与苯乙烯基乙二醛缩合生成14-苯基-9,12-二氧代-11-羟基四十四烯酸,经环化反应得到3-羟基-5-氧代-2-苯乙烯基环戊-1-烯庚酸。对苯乙烯基双键进行羟化反应,得到相应的2-(α,β-双羟基苯乙基)衍生物。用(-)或(+)-O-甲基曼德酰氯分离外消旋的2-苯乙烯基-3-羟基化合物,得到对映体,通过色谱分离。这些化合物可用作抗微生物、抗真菌和降压剂,作为前列腺素(PGE.sub.2)拮抗剂,也可用作前列酸衍生物及其对映体的中间体,这些对映体具有抗微生物、胃蛋白酶抑制、降压和平滑肌收缩特性。
