provide the correct geometry of these derivatives. Structural considerations among the possible isomers of compounds 1 are discussed. From these studies it was concluded that the theoretical calculations agree with the experimental results. In addition, a very simple one-pot procedure for the preparation of masked N-substituted alpha-alkylated beta-enamino acidderivatives 2 from 6, 7, and different alkyl

Synthetic approaches are developed to benzimidoylphosphoryl derivatives containing electronically and sterically diverse alkyl substituents on the nitrogen atom, as well as their prototropic isomers. Regularities in prototropic transitions in the phosphorylated C=N-C triad were revealed and applied in the synthesis of α-aminophosphonic acid derivatives.
