An efficient synthesis of series of benzoxazinones, employing sodium perborate tetrahydrate (SPB) as a condensing agent is described. SPB in water and formic acid system is proved as a selective catalyst of hydration for cyanides. The rate enhancement and high yield is attributed to the coupling of suitable catalyst with this solvent system. This methodology eliminates the number of steps during the reaction.
