For the first time in the benzodiazinium ylide series cycloaddition of (4-halophenyl) substituted ylides to activated alkenes and alkynes was studied. The ability of these ylides to react with acrylonitrile, N-phenylmaleimide, ethyl propiolate and dimethyl acetylenedicarboxylate was investigated. The stereochemistry and regiochemistry involved in these reactions are also discussed. Two new salts and ten new azabicyclic compounds have been obtained.
在苯并二氮杂环亚胺叶立德系列中,首次研究了(4-卤苯基)取代叶立德与活化烯烃和炔烃的环加成反应。这些叶立德与丙烯腈、N-苯基马来酰亚胺、丙炔酸乙酯和二甲基乙炔二羧酸酯反应的能力得到了调查。还讨论了这些反应涉及的立体化学和区域化学。已获得两种新盐和十种新的氮杂双环化合物。
