二氟卡宾与O-酰化水杨醛的芳基亚胺和烷基亚胺反应生成的含氟甲亚胺叶立德通过酯羰基发生分子内1,3-偶极环加成反应,得到2,8-二氧杂-6-氮杂双环[3.2.1]辛烷衍生物。
Fluorinated azomethine ylides generated by the reaction of difluorocarbene with aryl and alkyl imines of O-acylated salicylaldehyde undergo intramolecular 1,3-dipolar cyclo-addition across the ester carbonyl to give 2,8-dioxa-6- azabicyclo[3.2.1]octane derivatives.
