A structure–activity relationship study of ring C‐functionalized derivatives of the cytotoxic marine natural product(–)‐dibromophakellstatin from the spongePhakellia mauritianais reported. Functionalization of the pyrrolidine ring was achieved starting from the hydroxy derivative by conversion to the triflate followed by etherification by epimerizing nucleophilic substitution. We identified (12R)‐dibromo‐12‐hydroxyphakellstatin as the most cytotoxic derivative, which exhibited an average IC50value of 1.4 μMagainst a panel of twelve human cancer cell lines. However, the 12Sdiastereomer was inactive. Dehydrophakellstatin was synthesized as the first example of a phakellin skeleton with an unsaturated ring C.
