Abstract Simple stereospecific syntheses of 2-fluorohexanoic acid 5 were accomplished by conversion of optically pure L-(+)-norleucine to the optically pure hydroxy acid 3 via the classic diazotization reaction followed by substitution of the hydroxy functionality by the fluoro group. This was accomplished stereospecifically using DAST reagent or more practically by nucleophilic displacement of the
摘要 通过经典的重氮化反应将光学纯的 L-(+)-正亮氨酸转化为光学纯的羟基酸 3,然后用氟基团取代羟基官能团,从而实现了 2-氟己酸 5 的简单立体定向合成。这是使用 DAST 试剂立体特异性地完成的,或者更实际地是通过用氟离子亲核取代相应的甲磺酰氧基来完成的。
