Improved processes for producing substituted benzo(chalcogeno)[4,3,2-cd] indazoles. The processes produce compounds in higher yields and of greater purity by using a novel sequence of acylation chemistry and easily removed protecting groups. The compounds produced have antibacterial, antifungal, antileukemic, and antitumor activity.
