An efficient strategy toward 4-arylquinolines and 4-arylpyrimidines from readily available precursors is described. Oxidative annulation promoted by K2S2O8 involving anilines, aryl ketones, and DMSO as a methine (=CH-) equivalent leads to 4-arylquinolines via a cascade that entails generation of a sulfenium ion, subsequent C-N and C-C bond formations, and cyclization. The application of this strategy to the activation of acetophenone-formamide conjugates toward the synthesis of 4-arylpyrimidines is also described.

Two series of Sorafenib derivatives bearing phenylpyrimidine–carboxamide moiety (16a–g and 17a–p) were designed, synthesized and evaluated for the IC50values against three cancer cell lines (A549, MCF-7 and PC-3). Two selected compounds (17f and 17n) were further evaluated for the activity against VEGFR2/KDR kinase. More than half of the synthesized compounds showed moderate to excellent activity against three cancer cell lines. Compound 17f showed equal activity to Sorafenib against MCF-7 cell line, with the IC50values of 6.35 ± 0.43 μM. Meanwhile, compound 17n revealed more active than Sorafenib against A549 cell line, with the IC50values of 3.39 ± 0.37 μM. Structure–activity relationships (SARs) and docking studies indicated that the second series (17a–p) showed more active than the first series (16a–g). What's more, the introduction of fluoro atom to the phenoxy part played no significant impact on activity. In addition, the presence of electron-donating on aryl group was benefit for the activity.
