naphthylisoquinoline, pindikamine A (3), as a ‘skew’ analog of antiviral michellamines, is described. Because of the unusual coupling positions, this C2-symmetric quateraryl is the first michellamine analog without axial chirality. Key steps of the total synthesis are the preparation of the molecular precursor 9 by intermolecular biaryl coupling, followed by a highly efficient oxidative ‘dimerization’
描述了一种非天然的二聚萘基异喹啉,pindikamine A(3)的合成,它是抗病毒michellamines的“歪斜”类似物。由于不寻常的偶合位置,该C 2对称的季四芳基是第一个没有轴向手性的蜜三胺类似物。总合成的关键步骤是通过分子间联芳基偶合制备分子前体9,然后进行高效的氧化“二聚”以生成8,然后将其转化为3。品地敏A(3)及其单体“半” 10在体外对恶性疟原虫表现出良好的抗疟疾活性。
