Seven new 5,7-disubstituted oxine derivatives have been synthesized via a Mannich reaction between a sec. amine (e.g. piperidine, pyrrolidine, morpholine, or dibenzylamine,) and 5-cyano or 5-azidomethyl-8-hydroxyquinoline, which were respectively obtained by nucleophilic displacement of 5-chloromethyl-8-hydroxyquinoline by cyanide or azide anions. In all cases, a single product was isolated in medium to
通过几秒钟之间的曼尼希反应,已经合成了七个新的5,7-二取代的肟衍生物。胺(例如哌啶,吡咯烷,吗啉或二苄基胺)和5-氰基或5-叠氮基甲基-8-羟基喹啉,分别通过氰化物或叠氮化物阴离子对5-氯甲基-8-羟基喹啉的亲核取代而获得。在所有情况下,均以中等至中等收率分离出单一产物,并基于1 H和13 C-NMR,MS和IR光谱数据进行表征。还报道了由5-氰基甲基-8-羟基喹啉和哌啶获得的产物的X射线结构。
