Abstract

Isatine 4 and its derivatives play an important role in the pharmaceutical and dye industry. Drugs containing isatine units cure diseases such as epilepsy [1], tuberculosis [2], and bulimia [3]. Isatin derivatives are furthermore employed as antibacterial [4] or antifugal [5] compounds or to treat inflammations [6]. Because of its importance, various synthetic routes to isatine and its derivatives have been developed. Although the large-scale synthesis of ...
