The synthesis of three 9,11-dideoxyprostaglandins in which the cyclopentane moiety is replaced by a six-membered ring, is described. Starting from phthalaldehydic acid (1) the aromatic PG-analogue, 7-[2-(3-hydroxy-(E)-1-octenyl)phenyl]heptanoic acid (9), was prepared in 7 steps in 49% overall yield. The cis-substituted cyclohexane PG-analogue, ethyl 7-[cis-2-(3-hydroxy-(E)-1-octenyl)cyclohexyl]heptanoate
描述了三个9,11-二脱氧前列腺素的合成,其中环戊烷部分被六元环取代。从邻苯二酸(1)开始,以7步制备芳族PG-类似物7- [2-(3-羟基-((E)-1-辛烯基)苯基]庚酸(9),总产率为49%。该顺式-取代的环己烷PG-类似物,7-〔顺-2-(3-羟基- (ë)-1-辛烯基)环己基]庚酸甲酯(34),在7个步骤由相同的获得53%的总收率起始原料1。的反式-取代的环己烷PG-类似物,乙基7- [反式-2-(3-羟基- (É由9-氰基-(E)-2-壬烯酸甲酯(12)以8个步骤合成)-1-辛烯基)环己基]庚酸酯(20),产率为34%。
