  The action of dilute hydrogen peroxide in aqueous alkaline solutions on compounds I-VI and XX produced derivatives of 2-iminooxazolidine-4-one, VII-XI and XXI. Their structures were demonstrated by spectral comparison with hydantoin derivatives XXII, XXIV and XXV, which were prepared from 2-aminoalkanedioic acids XXVIII, XXX and XXXI by reaction with potassium cyanate, followed by ring closure induced by a mineral acid. The structure of compound X was revealed by basic hydrolysis to 2-hydroxy-1,7-heptanedioic acid (XXVII) and by conversion of the latter, in an acid medium, into a derivative of oxazolidine-2,4-dione, XXIX. To elucidate the probable mechanism of the oxidative transformation, compound IV was converted by oxidation in an acid medium into the 5-hydroxy derivative XXXII. Exposure of the latter to an alkaline medium gave compound X. Bromination of acid IV with bromine, or with a mixture of potassium bromide and bromate in an acid solution, afforded the 5-bromo derivative XXXIV. Analogously, reaction of the acid IV with a mixture of hydrogen peroxide and hydrochloric acid gave the 5-chloro derivative XXXV. Boiling the compound XXXIV in aqueous sodium hydroxide led to the acid IV and a smaller amount of compound X. Reaction of the compound X with morpholine yielded the morpholine analogue XXXVI. In the screening for antineoplastic activity, compounds XXXII and XXXVI showed weak antitumors effects with some types of experimental tumors. Compound X was quite ineffective in the general pharmacological screening.

  在水性碱溶液中稀释的过氧化氢对化合物I-VI和XX的作用产生了2-亚胺氧氮杂环-4-酮衍生物VII-XI和XXI。它们的结构通过与由2-氨基脂肪酸XXVIII、XXX和XXXI与氰酸钾反应后由矿酸诱导的环合反应制备的脲衍生物XXII、XXIV和XXV的光谱比较得到证明。化合物X的结构通过碱性水解成2-羟基-1,7-庚二酸（XXVII）和后者在酸性介质中转化为2,4-二酮-亚胺氧氮杂环衍生物XXIX来揭示。为了阐明氧化转化的可能机制，化合物IV在酸性介质中氧化成5-羟基衍生物XXXII。将后者暴露在碱性介质中得到化合物X。将酸性IV与溴或在酸性溶液中的溴化钾和溴酸混合物反应得到5-溴衍生物XXXIV。类似地，将酸性IV与过氧化氢和盐酸混合物反应得到5-氯衍生物XXXV。将化合物XXXIV在水性氢氧化钠中加热可得到酸性IV和少量化合物X。将化合物X与吗啡啶反应可得到吗啡啶类似物XXXVI。在抗肿瘤活性筛选中，化合物XXXII和XXXVI对某些实验性肿瘤表现出微弱的抗肿瘤效果。化合物X在一般药理筛选中效果不佳。
