Summary.

 Cyclohexane- and norbornanelactones (1, 5) as well as ketallactones (3, 7) and their hydrolytic products (2, 4a,b, 8) react with hydrazine hydrate to yield the hydroxy-substituted hexahydrophthalazinones 9–12. In the cyclizations, the configurations of the bridgehead atoms remain unaltered, and the hydroxy group retains its original position in the hydrazinolysis of 5 and 7. The compounds were characterized by IR, 1H, and 13C NMR spectroscopy.
