Abstract

The structure and the stereochemistry of the mono-adducts, obtained by 1, 3-dipolar cycloaddition of nitrile oxides to cyclooctatetraene, have been elucidated on chemical evidence. Thermolysis of their Diels-Alder adducts with acetylenedicarboxylate yielded 4- aryl (or alkyl)-2, 3-oxazabicyclo [3.2. 0] hepta-3, 6-dienes. Some reactions of this new heterocyclic condensed system are described.
