Abstract
Abstract Three new Schiff bases have been synthesised from the reaction of salicylaldehyde with the plant amino acids l -2-amino-3-methylaminopropanoic acid ( l -MeDAP), dl -2,4-diaminobutanoic acid ( dl -DAB) and dl -2,3-diaminopropanoic acid ( dl -DAP). The reaction of salicylaldehyde with l -MeDAP gave only the 2- (α-) product. The reaction of salicylaldehyde with dl -DAB or with dl -DAP produced, at equilibrium, predominately the 4- (ω-) or 3- (β-) species. X-ray single-crystal structures were determined for two compounds.
