Previously unknown amidophosphorous acid derivatives were prepared by transamidation of tert-butyl N,N-diethyl-N'-(4-phenylthiazolyl)phosphorodiamidite with 2-amino-4-phenylthiazole, and their reactions with acetyl and benzoyl chloride were studied. These reactions are shown to proceed regioselectively according to the Arbuzov scheme to give the corresponding ketophosphonates. The reaction of the phosphorodiamidite with acetyl chloride in a I : 2 molar ratio involves formation of acetophosphonate that reacts in the enol form to give the corresponding (1-acetoxy)vinylphosphonate.

Thiazolyl-containing esters of alpha-ketophosphonic acids (KPE) unknown earlier were synthesized and investigated in Darzens-Claisen reaction. Reactions were demonstrated to proceed by a classic scheme to form the corresponding phosphorylated glycidol esters whose alkaline hydrolysis gave rise to phosphorylated aldehydes of interesting nature.
