We describe a five-step synthesis of a PGH2 analogue from (R)-glyceraldehyde acetonide via formation of 1,2(S)-0-isopropylidene-hex-3(E)-en-5-one, conjugate addition of prostanoid C13- C20 side-chain as the cuprate with C1-C7 side-chain used to quench the resultant enolate, and finaily acid-catalysed ketal exchange to provide the desired analogue.
我们描述了通过(1,2)(S)-0-异亚丙基-hex-3(E)-en-5-one的形成,共轭添加类前列腺素从(R)-甘油醛丙酮化物中生成PGH 2类似物的五步合成方法C 13 -C 20侧链为具有C 1 -C 7侧链的铜酸盐,用于淬灭所得的烯醇化物,并经十一烷酸催化的缩酮交换以提供所需的类似物。
