Oxidation of readily-available semicarbazones of ketones with lead tetraacetate, followed by hydrolysis (insitu) of the products, makes novel Δ3-1,3,4-oxadiazolin-2-ones easily accessible. Spectra of the compounds are discussed and some of their potential for synthesis is indicated.
用四乙酸铅氧化容易获得的酮缩氨基脲,然后水解(原位)产物,使新的 Δ3-1,3,4-恶二唑啉-2-酮易于获得。讨论了化合物的光谱,并指出了它们的一些合成潜力。
