The utility of NaN3 as a reagent for the detosylation of N-tosylpyrroloiminoquinones and N-tosylindole-4,7-quinones is described. The NaN3-mediated detosylation is carried out in polar aprotic solvents such as DMF and DMSO. The reaction occurs under neutral, mild conditions and results in good to excellent yields of the detosylated quinones.
