The first representatives of the 2-alkyl-1,2,5-oxadiazol-3(2H)-ones have been synthesized by the alkylation of trimethylsilyl derivatives of 3-hydroxyfurazans using triethyl orthoformate. The compounds obtained are investigated by 13C,14N,15N and 17O NMR, MS, IR and UV.
通过使用原甲酸三乙酯使3-羟基呋喃酮的三甲基甲硅烷基衍生物烷基化,合成了2-烷基-1,2,5-恶二唑-3(2H)-ones的第一个代表。通过13 C,14 N,15 N和17 O NMR,MS,IR和UV研究所得化合物。
