  通过不同的反应条件，利用尿素对6-芳基-3-氰基-4-甲基硫基-2H-吡喃-2-酮进行环转化，展示了一种高效的一锅法合成2-氨基-6-芳基-4-甲基硫基吡啶和6-芳基-3-氰基-4-甲基硫基-2(1H)-吡啶酮。采用多种溶剂和碱分别选择性地制备2-氨基吡啶或2-吡啶酮。在无溶剂条件下直接将2H-吡喃-2-酮与尿素熔融时，两个产品以1:1的比例获得，而在吡啶中加热回流反应则专门生成2-氨基吡啶，产率为80-90%。在150°C下，6-芳基-3-碳甲氧基-4-甲基硫基-2H-吡喃-2-酮与尿素反应生成的2-吡啶酮衍生物产率良好（70-80%）。

The solvent effects on the UV–vis and fluorescence maxima were estimated by means of a series of ab-initio quantum chemical calculations in conjunction with Polarizable Continuum Model (PCM) method.

  M. tuberculosis thymidylate kinase (Mtb TMK) has been shown in vitro to be an essential enzyme in DNA synthesis. In order to identify novel leads for Mtb TMK, we performed a high throughput biochemical screen and an NMR based fragment screen through which we discovered two novel classes of inhibitors, 3-cyanopyridones and 1,6-naphthyridin-2-ones, respectively. We describe three cyanopyridone subseries that arose during our hit to lead campaign, along with cocrystal structures of representatives with Mtb TMK. Structure aided optimization of the cyanopyridones led to single digit nanomolar inhibitors of Mtb TMK. Fragment based lead generation, augmented by crystal structures and the SAR from the cyanopyridones, enabled us to drive the potency of our 1,6-naphthyridin-2-one fragment hit from 500 mu M to 200 nM while simultaneously improving the ligand efficiency. Cyanopyridone derivatives containing sulfoxides and sulfones showed cellular activity against M. tuberculosis. To the best of our knowledge, these compounds are the first reports of non-thymidine-like inhibitors of Mtb TMK.

  An efficient one-pot synthesis of 2-amino-6-aryl-4-­methylsulfanylpyridines and 6-aryl-3-cyano-4-methylsulfanyl-2(1H)-pyridinone has been illustrated through ring transformation of 6-aryl-3-cyano-4-methylsulfanyl-2H-pyran-2-ones by urea through different reaction conditions. Various solvents and bases were employed to selectively prepare either 2-aminopyridines or 2-pyridinones. In case of direct fusion of 2H-pyran-2-one with urea in solvent-free conditions, both the products were obtained in 1:1 ratio, while the reaction in pyridine at reflux temperature ex­clusively afforded 2-aminopyridine in 80-90% yield. The reaction of 6-aryl-3-carbomethoxy-4-methylsulfanyl-2H-pyran-2-ones with urea at 150 °C afforded 2-pyridinone derivatives in good yield (70-80%).
