The reaction of some 2-aminooxazoles and imidazolidin-2-ones with hydrogen peroxide afforded stable trans-β-hydroxyhydroperoxy- or dihydroperoxyimidazolidin-2-ones according to the reaction conditions. In the case of 3a-hydroxy-7a-hydroperoxyoctahydro-2H-benzimidazolidin-2-one, the trans isomer is forbidden and cis adduct was isolated. A radical pathway to these hydroperoxides is proposed. From 2-
根据反应条件,一些2-氨基恶唑和咪唑烷-2-酮与过氧化氢的反应提供了稳定的反式-β-羟基氢过氧-或二氢过氧咪唑烷-2-酮。在3a-羟基-7a-氢过氧八氢-2 H-苯并咪唑啉-2--2-的情况下,反式异构体被禁止并且顺式加合物被分离。提出了通向这些氢过氧化物的自由基途径。还从2-氨基-4-甲基恶唑和过氧化氢中分离出2-氨基-2-羟基-4-甲基恶唑烷丁-4-基过氧乙酸酯。
