A general method of the synthesis of ω-haloalkylphosphoryl compounds was developed, a series of compounds of phosphonic and phosphine oxide type were synthesized. The ability of some ω-haloalkylphosphonates to undergo intramolecular cyclization into the corresponding 1,2-oxaphospholane and 1,2-oxaphosphorine was investigated depending on the solvent polarity, the presence of halogen ions in the solution, and temperature. Tetrahydrofuran was chosen as one of the most suitable solvents for the alkylation of CH acids with ω-haloalkylphosphoryl compounds.

A new mild procedure of the amidoalkylation of hydrophosphoryl compounds in a mixture of acetic anhydride and acetyl chloride was developed as a convenient method of constructing the α-aminophosphoryl fragment of the pseudo-α,α′-dipeptide molecule. The reaction intermediates N,N′-benzylidene- and N,N′-alkylidenebiscarbamates were detected, isolated, and identified. The report presents the results of studying the direct interaction of hydrophosphoryl compounds previously synthesized with biscarbamates in acetic anhydride and other solvents, the influence of the structure of phosphorus component and biscarbamate, and the effect of acid catalysis on the course of this two-component reaction. A new version of the mechanism of the three-component reaction of amidoalkylation of hydrophosphoryl compounds is suggested: it is regarded as a multistage process involving the stage of biscarbamate formation followed by the stage of Arbuzov-type reaction with the intermediate formation of acyliminium cation and P-OAc derivative with trivalent phosphorus.

A new convenient synthesis of vinylphosphorylic derivatives was used to obtain phosphinothricine and other phosphorylic analogues of glutamic acid.
