<sup>1</sup>H and<sup>13</sup>C spectral assignment of substituted 5<i>H</i>-[1,3]thiazolo[2,3-<i>b</i>]quinazolin-5-one and 12<i>H</i>-[1,3]benzothiazolo[2,3-<i>b</i>] quinazolin-12-one

A concise construction of 12H-benzo[4,5]thiazolo[2,3-b]quinazolin-12-ones via an unusual TBHP/Na<sub>2</sub>CO<sub>3</sub> promoted cascade oxidative cyclization and interrupted Dimroth rearrangement
An interrupted Dimroth rearrangement was merged into the oxidative cyclization between isatins and 2-haloaryl isothiocyanates, giving 12H-benzo[4,5]thiazolo[2,3-b]quinazolin-12-one derivatives.
