摘要

Nucleophilic attack of sodium azide on isochrornylium salts leads to the preparation of l-azidoiso- chromenes which when heated lose molecular nitrogen and give 3-l-benzoxazepines. ... Thermolysis and photolysis of alkyl and aryl azides have been extensively studied in the last twenty years (1) but lit- tle attention has been paid to rearrangements of hetero- cyclic azides. We have shown that azidopyrans and azido- chromenes offer a ...
