total synthesis of (±)-cyclooroidin, a member of the pyrrole–imidazole alkaloid family recently isolated from the sponge Agelas oroides in optically pure form, is described. The synthesis was achieved in nine linear steps, with an overall yield of 10%. Key step was a Wolff bromoketone synthesis performed on the intermediate longamide B.
描述了(±)-cyclooroidin的第一个全合成,这是最近以光学纯净的形式从海绵Agelas oroides分离的吡咯-咪唑生物碱家族的成员。合成是通过9个线性步骤完成的,总收率为10%。关键步骤是对中间体长酰胺B进行Wolff溴酮合成。
