Starting from natural 4-hydroxyproline, an ex-chiral pool approach is described giving access to 2-aminoalkylpyrrolidine derivatives that were used as chiral building blocks for the synthesis of bioactive 2-methoxybenzamide derivatives. The 4-hydroxy substituent can be displaced employing organocuprates as useful carbanion equivalents. Dopamine and serotonin binding studies involving the subtypes D1
从天然的4-羟基脯氨酸开始,描述了一种手性前池方法,该方法可得到2-氨基烷基吡咯烷衍生物,该衍生物用作合成生物活性2-甲氧基苯甲酰胺衍生物的手性构件。可以使用有机铜酸盐作为有用的碳负当量置换4-羟基取代基。多巴胺和涉及亚型D1,D2血清素结合研究长,D2短,D3和D4,以及5-HT1甲和5-HT2,分别提供有趣的见解立体结构活性关系。(2 S,4 R)-2-氨基甲基吡咯烷衍生物ent -66和(2 R,4 S)-2-氨基乙基吡咯烷衍生物68分别显示出对多巴胺D3和D4受体亚型的显着亲和力和偏爱性,两者都被认为与精神分裂症的症状有关。
