Vinyl azetidines can be converted to nitro olefins , or to unsaturated aldoximes –, which are useful precursors for intramolecular nitrile oxide - olefin cycloadditions (INOC). Such INOC reactions proceed with a fair degree of stereoselectivity producing novel heterocycles.
乙烯基氮杂环丁烷可以转化为硝基烯烃,或与不饱和醛肟- ,它们是分子内氧化腈的前体有用的-烯烃环加成(INOC)。这样的INOC反应以相当大的立体选择性进行,从而产生新的杂环。
