Selenoisotryptophan and its higher homologues were synthesized by Sonogashira coupling of iodophenyl methyl selenide and alkynyloxazolidines followed by iodocyclization as the key step. Sonogashira coupling of 3-iodobenzoselenophene with ethynyloxazolidine allowed the synthesis of selenohomotryptophan.
硒异色氨酸及其高级同系物是通过碘苯基甲基硒化物和炔基恶唑烷的 Sonogashira 偶联合成,然后是碘环化作为关键步骤。3-碘苯并硒酚与乙炔恶唑烷的 Sonogashira 偶联允许合成硒高色氨酸。
