Three phosphinate salts (5), (6) and (7) were prepared as potential inhibitors of the enzyme pantothenate synthetase. The synthesis of compound (5) utilises a (diethoxymethyl)-protected phosphinate (8) as a new reagent for the formation of unsymmetrical phosphinic acids and esters. Initial P-alkylation of (8) followed by a selective deprotection sequence yields intermediate P-H phosphinates (16) and
