ω-haloalkylphosphoryl compounds: Synthesis and properties

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.

Phosphorus-containing aminocarboxylic acids: XII. Synthesis of unsaturated analogs

Methods for synthesis of 2-amino-5-phosphono-4-pentenoic and 2-amino-6-phosphono-4-hexenoic acids are proposed.
