Abstract

By the reaction of 1-ethynyl-1-aminocyclohexane with 3,4-dimethoxybenzaldehyde and n-aminodimethylbenzaldehyde, the corresponding Schiff bases were obtained, the phosphonylation of which by diethylphosphoric acid under the conditions of the Pudovik reaction, new α-aminophosphonates were isolated and characterized. The composition and structure of the synthesized compounds were investigated and confirmed by IR, NMR 1H, and 31P spectroscopy methods.
