Synthesis and mass spectral fragmentations of new spiro heterocycles
摘要:
The reaction of dichlorodiphenoxymethane (2) with orthio-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'-binaphthyl-2, 2'-diol gave the semi-cyclized derivative 2, 2-diphenoxydinaphthodioxepine 8.
