Abstract
A novel, highly efficient, and eco-friendly method is introduced for synthesizing 1,8-dioxo-decahydroacridines via a multicomponent reaction involving substituted aromatic aldehydes, 5,5-dimethyl-1,3-cyclohexanedione, and aromatic amines, utilizing guanidine hydrochloride (GdnHCl) as a catalyst. This environmentally sustainable approach eliminates the need for hazardous solvents and extensive purification procedures, offering a column-free, high-yield, energy-efficient solution. This method demonstrates exceptional environmental sustainability, characterized by high atom economy (88.66%), minimal waste generation (E-factor = 0.041), and an excellent Eco-scale score of 95, underscoring its eco-friendly nature. The catalytic system exhibits remarkable efficiency, with a turnover number (TON) of 40 and a turnover frequency (TOF) of 0.044 s⁻1, while maintaining its activity across multiple reaction cycles.
