The properties and spectroscopic characteristics of compound II were presented in [9], and compounds IIIa, IIIb were reported in [ 10]. Alkylation of compound I with bromoacetic acid ethyl ether or with ot-bromobutyric acid led to the previously undescribed dialkylamino derivatives, which were isolated in the form of hydrobromides: 3-N-(ethoxycarbonylmethyl)benzylamino-4-hydroxy-N-benzylbutanamide (IVa)
3-氨基-4-羟基丁酰胺是γ-羟基丁酸的多功能衍生物,可用于杂环化合物的靶向合成,包括含有恶唑烷环的结构。众所周知,7-羟基丁酸和许多含有恶唑烷片段的物质都具有抗菌特性[1 -4]。4-羟基丁酰胺可以被认为是在生物体内立即内酯化的前药,这会导致某些生物学效应[5, 6]。然而,对于 7-羟基丁酸是在生物体中以开放形式还是作为环状 γ-丁内酯存在,目前还没有普遍接受的意见 [5, 7, 8]。我们使用 3-benzylamino-4-hydroxy-N-benzylbutanamide (I) 合成了一系列新的含氨基甲酰基的 oxa(thia)zolidines (II, IIIa, IIIb) 和 4-羟基-3-二烷基氨基-N-丁酰胺(IVa、IVb)并研究了它们的抗菌特性。3-Benzyl-4-(N-benzylcarbamoylmethyl)-2-oxo1,2,3-oxathiazolidine
