The direct syntheses of two potencial anti-hypertensive drug candidates having the indole skeleton ( and ), using the β-cyanoaldehyde or a γ-amide-aldehyde in Fischer condesations with ϱ-methoxyphenylhydrazine are described. As by-products from these syntheses we isolated the chloropyrrole () and two diasteroisomeric molecules (-E and -Z), one of them leading selectivity to the N-acetylpyrrole . The
描述了在费歇尔定义中使用β-氰醛或γ-酰胺-醛与β-甲氧基苯基肼直接合成具有吲哚骨架(和)的两种潜在的抗高血压药物候选物。作为这些合成的副产物,我们分离了氯吡咯()和两个非对映异构分子(-E和-Z),其中一个导致对N-乙酰基吡咯的选择性。通过单晶X射线衍射研究证实了这三种次要产物(,-E和)的结构和立体化学。
