Indolones of the general formula 1 (Fig. 1 and 2) can act as Michael substrates, which readily add various nucleophiles. 1,4‐Addition of S‐nucleophiles to these indolones gives access to compounds of the general formula 2 (Fig. 2). The addition is reversible, meaning that these compounds behave as prodrugs of the (in‐vitro) cyto‐toxic indolones. The addition products possess less cytotoxicity of their
