Effect of alkyl chain length, head group and nature of the surfactant on the hydrolysis of 1,3-benzoxazine-2,4-dione and its derivatives.

Abdullah S Al-Ayed et al.

Journal of colloid and interface science, 361(1), 205-211 (2011-06-11)

The alkaline hydrolysis of carsalam (2H-1,3-benzoxazine-2,4(3H)-dione), denoted as I, and its N-substituted derivatives i.e., N-methyl-1,3-benzoxazine-2,4-dione (II) and N-benzoyl-1,3-benzoxazine-2,4-dione (III) was studied spectrophotometrically at physiological temperature. The rate of hydrolysis was found to be independent on the substrate concentration. In case

Hydrolysis kinetics of 1,3-benzoxazine-2,4-dione (a potential salicylamide prodrug) and various N-substituted derivatives.

Acta pharmaceutica Nordica, 3(1), 45-50 (1991-01-01)

The kinetics and mechanism of hydrolysis of 1,3-benzoxazine-2,4-dione and its N-methyl and N-benzoyl derivatives were studied in aqueous solution to provide basic information on the reactivity of the benzoxazinedione structure and to assess the potential of unsubstituted 1,3-benzoxazine-2,4-dione as a
