Herein, we report an efficient one-pot synthesis of bridged aminodiperoxides via a three-component reaction of 1,5-diketones with geminal bishydroperoxides and ammonium acetate. The synthesized aminodiperoxides are stable despite containing an unprotected secondary NH-group adjacent to two peroxide functionalities. Under optimal conditions, the reaction affords aminodiperoxides in high yields (up to 88%) with outstanding selectivity and high atom economy, thereby eliminating the need for column chromatographic purification. The synthesized aminodiperoxides exhibit potent cytotoxicity and remarkable selectivity toward Jurkat, K562, and A549 cancer cell lines, and are significantly superior to the clinically used anticancer agent camptothecin. Among all tested compounds, 3ec is the most promising candidate, exhibiting high activity and selectivity toward all tested cell lines (Jurkat: CC50 = 12.9 µM, SI = 67.09; K562: CC50 = 19.6 µM, SI = 44.28; A549: CC50 = 48.2 µM, SI = 17.98). Furthermore, a novel class of fungicidal compounds has been discovered. The aminodiperoxides exhibit fungicidal activity against phytopathogenic fungi, in some cases comparable to the commercial fungicide Triadimefon.
