The labile quinonylalkylenaminones 10a-c and 11a-c are synthesized and cyclized to the products 17, 21 and 22a-c. In solution the tricyclic systems 22a-c react to spirocompounds 19a-c and 20a-c. The structure of 22a is confirmed by X-ray analysis. Semiempiric quantum chemical calculations and Pearson's concept of hard and soft acids and bases are used to explain the observed reactions.
