An improved method for the synthesis of dolichyl H-phosphonate was developed using 2-chloro-4H-1,3,2-benzodioxaphosphorin-4-one (salicyl chlorophosphite) as a reagent. Dolichyl phosphorofluoridate was for the first time synthesized from dolichyl H-phosphonate by its treatment with chlorotrimethylsilane, oxidation with iodine, and subsequent interaction with fluoride ion in pyridine.
