Synthesis and Some Reactions of New Acetals Containing Aminoethylenephosphoryl Fragment

Phosphonoethylated amino acetals were synthesized for the first time by reacting vinylphosphonates with α- and γ-aminoacetals. The reaction of 2-methylresorcinol with the acetals in ethanol in the presence of hydrochloric acid afforded the first representative of diarylbutylamines containing β-aminoethylenephosphoryl fragment.
