Total synthesis of 2-(2-hydroxyalkyl)-piperidine alkaloids, (−)-halosaline and (−)-8-epi-halosaline is reported from n-butyraldehyde using iterative asymmetric allylation, nucleophilic substitution with an azide and ring-closing metathesis as the key reactions.
据报道,使用迭代不对称烯丙基化,叠氮化物的亲核取代和闭环复分解反应,从正丁醛中合成了2-(2-羟烷基)-哌啶生物碱,(-)-卤代碱和(-)-8-表卤代卤代碱。作为关键反应。
