Abstract: Trimolecular condensation of <i style="">N</i>-(3-methyl-5-styryl-4-isoxazolyl)-<i style="">N'</i>-aryl ureas <b style="">2</b>, paraformaldehyde and primary amines using montmorillonite K-10 in dry media under microwave irradiation leads to isoxazolyl-[1,3,5]-triazinan-2-ones <b style="">3</b> in high yields. Condensation of <b style="">2</b> with paraformaldehyde under similar condition provides isoxazolyl-[1,3,5]-oxadiazinan-4-ones <b style="">4</b> in excellent yields.
