Abstract An efficient method for the synthesis of phosphorated 1,2-oxazabuta-1,3-dienes derived from phosphine oxides and phosphonates has been developed by means of base-mediated dehydrohalogenation of readily available α-halooximes. New functionalized α-amino phosphorus derivatives are easily available, in a regioselective way, through conjugate addition of amino nucleophilic reagents such as ammonia
