Caprazamycins are the lead compound for CPZEN-45, which exhibits activity against extensively drug resistant tuberculosis (XDR-TB) and is currently under preclinical studies. The development of an efficient synthetic route to caprazamycins and related compounds is expected to facilitate structure-activity relationship studies on anti-TB agents. This review summarizes current synthetic strategies for caprazamycins, liposidomycins, caprazol, and CPZEN-45, with a particular focus on stereocontrol and diazepanone ring formation.
