The cover picture shows a green and highly efficient synthetic method for the synthesis of quinazoline‐2,4‐diones from readily available isatins and arylamines. This method is interesting in keeping with the notion of green chemistry because of the use of hydrogen peroxide as the terminal oxidant. The rearrangement oxidation exhibited good functional group tolerability, metal‐free catalysts, obviating the need for oxidants and only environmentally benign H 2 O was released. Moreover, an antibacterial activity study was performed to evaluate the antimicrobial activities. The results showed that some of the testing compounds inhibited the growth of the Staphylococcus aureus (32 μg/mL) and Staphylococcus epidermidis (64 μg/mL), which could potentially solve the problem of multidrug resistance. More details are discussed in the article by Shang et al. on page 1835–1843.
