1-Hexadecyl-2-palmitoylglycero-3-phosphodichloride was quntitatively o
btained in the reaction of an appropriate glycerol derivative with an
excess phosphoryl chloride in the presence of amine at 0-3 degrees C,
and its structure was confirmed at low temperature H-1, C-13, and P-31
NMR. The substance proved to be stable ina chloroform solution at 0-3
degrees C and, thus, useful for preparative syntheses. At room temper
ature in the acidic medium, it was revealed that the compound prepared
undergoes hydrolytic degradation, which includes the splitting of a p
hosphodiester bond, the migration of its 2-acyl group to the position
3 in the glycerol backbone, and chlorination. At 0-3 degrees C, its ba
sic hydrolysis (e.g., in the presence of triethyamine or KHCO3) result
ed in the formation of the corresponding salts of phosphatidic acid.
