An efficient synthetic route to the putative biosynthetic intermediate of the anti-plasmodial natural product janoxepin is described. This novel enamine-containing pyrazino[2,1-b]quinazoline-3,6-dione, and its synthetic precursors, should be of value in studies to elucidate the biosynthetic pathway leading to the oxepine family of natural products. The cornerstones of the synthesis are amide coupling
描述了一种抗疟原虫天然产物janoxepin的推定生物合成中间体的有效合成途径。这种新型的含烯胺的吡嗪并[2,1 - b ]喹唑啉-3,6-二酮及其合成前体,在阐明导致天然产物奥沙平家族的生物合成途径的研究中应具有价值。合成的基础是酰胺偶联,吡嗪并[2,1 - b ]喹唑啉-3,6-二酮结构和烯胺的羟醛引入。
