EFFICIENT SYNTHESIS OF 2,3-DIHYDROQUINOXALINE-4 1H -ONE DERIVATIVES USING ZIRCONIUM TETRAKIS DODECYL SULFATE [ZR DS 4] AS AN LEWIS ACID MICELLAR AND REUSABLE CATALYST IN WATER

2,3-Dihydroquinazolin-4(1H)-ones have been synthesized in the high to excellent yields via condensation of 2-aminobenzamide with aldehydesand ketones in the presence of catalytic amount of[Zr(DS)4] in H2O as a green media at at room temperature . Mild reaction conditions, clean reactionmedia, simple workup and relatively shortreaction times and easy purification are advantages of this methodology
