By the reaction of diacetyl with cyanohydrines derived from ketones 2,2-di-hydroxyacyl-amino-3-keto-n-butanes (3–6) and 2-methyl-2-acetyl-oxazolidones-(4) (3a–6a) were obtained. The structure of these compounds were confirmed by further chemical transformation and by comparison of infrared spectra with 2,2,5,5-tetra-alkyl-4-oxazolidones prepared by an independent route.
通过二乙酰基与衍生自酮2,2-二羟基酰基-氨基-3-酮-正丁烷(3-6)和2-甲基-2-乙酰基-恶唑烷酮-(4)(3 a–获得6 a)。通过进一步的化学转化并通过将红外光谱与通过独立途径制备的2,2,5,5-四烷基-4-恶唑烷酮进行比较,确认了这些化合物的结构。
