1,3-Dipolarcycloaddition of benzyne with 3-oxo-l,2-diazetidinium hydroxide, inner salts leads to tricyclicadducts which have been termed “bicyclobenzodiazepinones” because of their structural relationship to 1,4-benzodiazepinones. In analogous fashion, cycloaddition of benzyne with 3-oxopyrazolidinium hydroxide, inner salts, leads to homologous tricyclicadducts. Efforts to convert these readily

The gold-catalyzed [3+3]-cycloaddition reaction of propargyl. esters and azomethine imines has been developed. The reaction provides a rapid entry into a wide range of substituted tetrahydropyridazine derivatives from simple starting materials. A stepwise mechanism involving addition of the 1,3-dipole to a gold-carbenoid intermediate is proposed.
