The synthesis of 2‐(4‐amino‐2‐alkylaminothiazol‐5‐oyl)benzothiazoles and 2‐[2,4‐bis(arylamino)thiazol‐5‐oyl]benzothiazoles as benzothiazoloylthiazole analogs of the cytotoxic marine alkaloid dendrodoine is reported. The highly decorated thiazole ring assembly was achieved using 2‐bromoacetybenzothiazole to supply the C5 ring carbon and amidinothioureas of the type R1NHCSNHC(NHR2)(NHR3) to provide the four ring atoms [C4N3C2S1] in a [4+1] thiazole ring construction strategy. The antibacterial activity of these new analogs is reported. J. Heterocyclic Chem., (2010).
