Oxazolidine-2,4-diones were synthesised by tetraethylammonium hydrogen (TEAHC) promoted carboxylation of secondary carboxamides bearing a leaving group at the α-position. Several oxazolidine-2,4-diones, including clinically used malidone, have been prepared in moderate to excellent yields as a results of a formal proton extraction-carboxylation- intramolecular S(N)2 one-pot sequence.
