Various (hetero)arenecarboxylic acids were converted to the corresponding Daugulis amides and nitrated selectively in the ortho‐position in the presence of [CuNO3(PPh3)2] and AgNO2 at 50 °C. A microwave‐assisted saponification allows regenerating the carboxylate group within minutes, which may then be removed tracelessly by protodecarboxylation, or substituted by aryl‐ or alkoxy‐groups via decarboxylative
Prodrugs of cyclic anthracyclin toxins comprising a hypoxia-activated trigger and are disclosed. In addition, methods of treating cancer using the compounds of the invention are disclosed.
