Treatment of 2,3,3-triphenyl-4-formylisoxazolidines with bases triggers an unprecedented anionic reactional cascade which terminates with a 2-iminooxetane derivative. In the case of 2,3,3-triphenyl-4-methoxycarbonyl isoxazolidine the multistep rearrangement gives rise to a derivative of malonic acid.
用碱处理2,3,3-三苯基-4-甲酰基异恶唑烷会触发前所未有的阴离子反应级联反应,并以2-亚氨基氧杂环丁烷衍生物终止。在2,3,3-三苯基-4-甲氧基羰基异恶唑烷的情况下,多步重排产生丙二酸的衍生物。
