The synthesis and examination of the steric structure and physiological activity of y-piperidones and y-piperidols have been the subject of many reports [8, 10, 12]. There is, however, little information on 4-oxo(hydroxy, amino)piperidines with aryl substituents in the a,~',8-positions. A modified Mannich reaction [9, ii, 13] has been used to obtain some novel 3-phenyl-2,6-diaryl-4-oxopiperidines.
γ-哌啶酮和γ-哌啶醇的空间结构和生理活性的合成和检测已成为许多报道的主题[8, 10, 12]。然而,关于在 a,~',8-位具有芳基取代基的 4-氧代(羟基,氨基)哌啶的信息很少。改进的曼尼希反应 [9, ii, 13] 已被用于获得一些新的 3-苯基-2,6-二芳基-4-氧代哌啶。苯甲醛、对-溴-和对-甲氧基苯甲醛和水杨醛已与甲基苄基酮或甲基8-苯乙基酮和氨或甲胺缩合。为了从γ-哌啶酮(I、II、IV-VI)获得具有杀菌、杀真菌和除草活性的化合物,获得了它们的肟(XVI-XX)和仲γ-哌啶醇(IX-XIV)。肟被还原成胺(XXII-XXV)。
