Manganese(III)-catalyzed aerobic oxidation of combinations of 3-(2-oxoethyl)piperidine-2,4-diones and 1,1-diarylethenes at room temperature produced structurally interesting trioxa-aza[4.4.3]propellanes in good yields. Similar reactions using 2-(2-oxoethyl)cyclohexane-1,3-diones also produced the corresponding endoperoxy[4.4.3]propellanes. On the other hand, 3-oxopropyl-substituted cycloalkane-1,3-diones
在室温下,锰 (III) 催化的 3-(2-氧乙基)哌啶-2,4-二酮和 1,1-二芳基乙烯的组合的有氧氧化以良好的产率产生结构有趣的三氧杂氮杂 [4.4.3] 推进烷。使用 2-(2-氧乙基)环己烷-1,3-二酮的类似反应也产生了相应的内过氧 [4.4.3] 推进剂。另一方面,3-氧代丙基取代的环烷烃-1,3-二酮没有得到所需的推进烷,而是以极好的产率形成了1,2-二氧杂双环推进烷前体。在路易斯酸的存在下,前体可以转化为相应的推进剂。还描述了形成推进剂的机制。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
