A PhI(OAc)2-promoted dioxygenation of allyl oximes, including one alkoxylation, has been developed. This reaction can give isoxazoline products bearing two contiguous tetrasubstituted carbons. Various oximes substrates bearing different aryl groups and tetrasubstituted-olefin moieties were compatible with the mild reaction conditions. A two-electron oxidation pathway was proposed based on results of
已经开发了由PII(OAc)2促进的烯丙基肟的双加氧反应,包括一种烷氧基化反应。该反应可以得到带有两个连续的四取代碳的异恶唑啉产物。带有不同芳基和四取代烯烃部分的各种肟底物与温和的反应条件相容。基于初步机理研究的结果,提出了一种双电子氧化途径。
