| Abstrakt: |
A new method of spiro-ring formation by the reaction of s-tetrazines with anhydro bases was described. The prototropic transitions were detected in the pyridazine fragments of the resulting spirocyclic compounds. The heterocycles of the anhydro bases are converted to cyclic ketones as a result of the breaking of the spiro junction in the acidic hydrolysis of the spirohetarenes. The regioselectivity of the cycloaddition was established. |
