A convenient method for the synthesis of 2-azido-3-arylpropanoic acids via the Meerwein halogenoarylation reaction of acrylic acidesters with diazonium salts, subsequent nucleophilic substitution of the halogen by an azide, and saponification is developed. The newly formed 2-azido-3-arylpropanoic acids react under the conditions of non-catalytic four-component Ugi reactions, leading to the formation
开发了一种通过丙烯酸酯与重氮盐的 Meerwein 卤代芳基化反应、随后用叠氮化物对卤素进行亲核取代和皂化来合成 2-叠氮基-3-芳基丙酸的简便方法。新形成的 2-叠氮基-3-芳基丙酸在非催化四组分 Ugi 反应条件下反应,以良好的收率形成 α-叠氮基酰胺。使用炔丙基胺作为胺组分可以形成具有叠氮化物和乙炔基序的 Ugi 加合物,可用于分子内 1,3-偶极 Huisgen 环加成反应,得到 [1,2,3]三唑并[1,5- a ]吡嗪环化体系. 发现 Ugi 反应得到 2-叠氮基-3-芳基-N- (2-氧代-1,2-二取代乙基) -N-(prop-2-yn-1-yl)propanamides 在室温下没有叠氮化物-炔烃环加成。通过在甲苯中加热,这些二肽以接近定量的产率转化为 4,5-二氢[1,2,3]三唑并[1,5 - a ]吡嗪-6(7 H )-酮。然而,当 Ugi 反应通过加热进行时,它会导致一锅
