| 摘 要： | The reaction of dichlorodiphenoxymethane (2) with ortho-functionlized benzoic acids 1a-c yielded the spiro derivatives of bezodioxinone 4a, benzoxazinone 4b and benzodioxepinone 4c. The same reaction with 1,8-diaminonaphthalene afforded the spiro perimidine 6, while with 1,1'-binaphthy1-2,2'-diol gave the semi-cyclized derivative 2,2-diphenoxydinaphthodioxepine 8.
