This study introduced a solvent-free synthesis of 1,8-dioxodecahydroacridine derivatives through a one-pot condensation reaction involving cyclic 1,3-diketone and aldehydes, utilizing sulfated tin oxide (STO) as a heterogeneous catalyst, achieving yields of up to 93%. The current methodology presents numerous advantages, including low cost, a recoverable and reusable catalyst (up to three times), a solvent-free strategy, straightforward setup, high yield, and reduced reaction time, effectively highlighting the environmentally friendly nature of the present reaction.
