Synthesis of novel bis(β-aminocarbonyl) compounds and some β-aminocarbonyls by catalyst-free multicomponent Mannich reactions
A highly diastereoselective catalyst-free multicomponent Mannich reaction between cyclohexanone, aromatic aldehydes and amines in cyclohexane is described. The double Mannich reaction of diamines and two equivalents of aldehydes and cyclohexanone gave the
Synthesis, spectroscopic and cytotoxic studies of biologically active new Schiff bases derived from p-nitrobenzaldehyde
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 the test animal.
