The reaction of trialkyl phosphites with alkyl malonyl chlorides leads to alkyl 3-dialkoxyphosphoryl-3-oxopropionates, which exist in the stable E-enol form. Depending on the basicities of the bases, the reactions of alkyl 3-dialkoxyphosphoryl-3-oxopropionates with nitrogen bases proceed with retention of the C-P bond and the formation of phosphorylated azomethine derivatives or with cleavage of the C-P bond and the liberation of nitrogen-containing derivatives of malonic acid. The /sup 1/H, /sup 13/C, and /sup 13/P NMR spectra were recorded with a Bruker WP-80 NMR spectrometer. The chemical shifts of the protons and carbon atoms are presented relative to tetramethylsilane (TMS). The chemical shifts of the /sup 31/P nuclei were determined relative to H/sub 3/PO/sub 4/.
