A novel synthetic route was developed for the construction of isoxazolin-5-one glucosides using a cascade reaction. An X-ray crystal structure analysis of a isoxazolin-5-one glucoside confirmed the structure and stereochemistry of the heterocycle. The properties of the α- and β-anomers of the isoxazolin-5-one glucosides were compared. The first synthesis of 2-[6′-(3″-nitropropanoyl)-β-d-glucopyran
开发了一种新的合成途径,用于使用级联反应构建异恶唑啉-5-酮糖苷。异恶唑啉-5-酮葡糖苷的X射线晶体结构分析证实了杂环的结构和立体化学。比较了异恶唑啉-5-酮糖苷的α-和β-端基异构体的性质。2- [6'-(3″-硝基丙酰基)-β - d-吡喃葡萄糖基] -3-异恶唑啉-5-酮的第一次合成是通过直接酶促酯化反应实现的,不需要其他保护基。
