A novel three-component, two-step, one-pot nucleophilic aromatic substitution (S_NAr)–intramolecular cyclization–Suzuki coupling reaction was developed for the synthesis of benzo[h][1,6]naphthyridin-2(1H)-ones (Torins). On the basis of the new efficiently convergent synthetic route, a library of Torin analogs was synthesized. The antimalarial activities of these compounds were evaluated against asexual parasites using a growth inhibition assay and gametocytes using a viability assay.

1,9取代的苯并[ h ] [1,6]萘啶-2（1 H）-酮的有效合成及其对恶性疟原虫的杀细胞活性的评价

为合成苯并[ h ] [1,6]萘啶-2（1 H），开发了一种新颖的三组分，两步，一锅亲核芳香取代（S _N Ar）-分子内环化-Suzuki偶联反应。-一个（Torins）。在新的有效收敛的合成路线的基础上，合成了都灵类似物的文库。使用生长抑制测定法评估这些化合物对无性寄生虫的抗疟活性，并使用生存力测定法评估配子细胞。
