  Switching between Reaction Pathways by an Alcohol Cosolvent Effect: SmI₂–Ethylene Glycol vs SmI₂–H₂O Mediated Synthesis of Uracils

  摘要：

  A chemoselective switch between reaction pathways by an alcohol cosolvent effect in a general SmI2-mediated synthesis of uracil derivatives is described. The method relies on the use of coordinating solvents to increase the redox potential of Sm(II) and results in a chemoselective 1,2-reduction (SmI2H2O) or 1,2-migration via in situ generated N-acyliminium ions (SmI(2)ethylene glycol, EG). This work exploits the mild conditions of the SmI2-mediated monoreduction of barbituric acids and offers an attractive protocol for the synthesis of uracil derivatives with biological activity from readily accessible building blocks.

  巴比妥酸的单C-烷基化和单C-苄基化，通过锌/酸还原酰基，亚苄基和亚烷基巴比妥酸酯中间体

  摘要：

  通过系统地研究反应条件，开发了用于获得大量取代的5-烷基和5-苄基巴比妥酸的非常有效的制备方法。该过程包括两步准备，其中第二步是还原锌粉/酸。对于制备5-烷基巴比妥酸酯，第一步是制备5-酰基或5-亚烷基巴比妥酸酯。如果5-苄基巴比妥酸酯是目标产物，则第一步包括制备5-亚苄基。无论第一步的性质如何，所有反应的合成产率均约为90％，而分离和纯化仅涉及结晶。

  A one-pot two-step reaction (Knoevenagel condensation – reduction of the double bond) has been developed using calcium hydride as a reductant in the presence of a supported noble metal catalyst. The reaction between carbonyl compounds and active methylene compounds such as methylcyanoacetate, 1,3-dimethylbarbituric acid, dimedone and the more challenging dimethylmalonate, affords the corresponding

  dearomatizing radical cyclizations and cyclization cascades, triggered by single electron transfer to amide-type carbonyls by SmI2-H2O-LiBr, provide efficient access to unprecedented spirocyclic scaffolds containing up to five stereocenters with high diastereocontrol. The first dearomatizing radical cyclizations involving radicals derived from amide carbonyls by single electron transfer take place under

  Urea‐type carbonyls in barbiturates undergo a highly chemoselective electron transfer reduction upon treatment with SmI2/H2O/LiBr. The process involves the formation, and further reduction, of unusual ketyl‐type radical anions under mild conditions. Cyclic aminal products are obtained in good to excellent yield without recourse to preactivation of the substrate or the use of metal hydride reagents

  Opportunistic fungal infections caused by the Candida spp. are the most common human fungal infections, often resulting in severe systemic infections-a significant cause of morbidity and mortality in at-risk populations. Azole antifungals remain the mainstay of antifungal treatment for candidiasis, however development of clinical resistance to azoles by Candida spp. limits the drugs' efficacy and highlights the need for discovery of novel therapeutics. Recently, it has been reported that simple hydrazone derivatives have the capability to potentiate antifungal activities in vitro. Similarly, pyrimidinetrione analogs have long been explored by medicinal chemists as potential therapeutics, with more recent focus being on the potential for pyrimidinetrione antimicrobial activity. In this work, we present the synthesis of a class of novel hydrazone-pyrimidinetrione analogs using novel synthetic procedures. In addition, structure-activity relationship studies focusing on fungal growth inhibition were also performed against two clinically significant fungal pathogens. A number of derivatives, including phenylhydrazones of 5-acylpyrimidinetrione exhibited potent growth inhibition at or below 10 mu M with minimal mammalian cell toxicity. In addition, in vitro studies aimed at defining the mechanism of action of the most active analogs provide preliminary evidence that these compound decrease energy production and fungal cell respiration, making this class of analogs promising novel therapies, as they target pathways not targeted by currently available antifungals.
