The first synthesis of cyclic benzopyridoiodolium salts is described. These hypervalent iodine intermediates are used in an efficient strategy for the construction of the δ-carboline core. This novel approach involves a twofold palladium-catalyzed Buchwald-Hartwig reaction between these unprecedented reagents and a primary amine. Our methodology successfully provides the expected N-substituted δ-carboline
描述了环状苯并吡啶鎓盐的第一合成。这些高价碘中间体被用于构建δ-咔啉核的有效策略中。这种新颖的方法涉及这些前所未有的试剂和伯胺之间的钯催化的双重Buchwald-Hartwig反应。我们的方法成功地提供了预期的N-取代的δ-咔啉核,并有效地应用于喹啉的全合成。 生物碱-胺化-杂环-碘-全合成
