The potential hydroacridinone synthesis using simple and inexpensive starting materials, namely 1,3-dicarbonyl compounds, anilines, formaldehyde and DBU as a stoichiometric base was explored. As a result, from the reaction of 1,3-cyclohexanedione and dimedone tetrahydroacridinones were the main reaction products along with small yields of their oxidation products, the dihydroacridinones, whereas in the case of 2-acetylcyclohexanone spirohexahydropyrimidines were isolated in very good yields. Plausible mechanistic schemes for the formation of all products are proposed.
