Thirteen new Schiff bases derived from p-nitrobenzaldehyde were synthesized by condensation with the appropriate amines. An unusual reduction of the p-nitrobenzaldehyde to the corresponding alcohol was also observed in one of the reactions. The structures of the compounds were identified using spectroscopic techniques. Cytotoxicity for the titled compounds was studied against Brine Shrimp, used as
AbstractA highly diastereoselective catalyst-free multicomponent Mannichreaction between cyclohexanone, aromatic aldehydes and amines in cyclohexane is described. The doubleMannichreaction of diamines and two equivalents of aldehydes and cyclohexanone gave the novel bis(β-aminocarbonyl) compounds. Reactions proceeded in good to high yields with an excellent diastereoselectivity. The best selectivity
