  The synthesis and structure–activity relationships of 1,3-diaryl 1,2,4-(4 H )-triazol-5-ones: A new class of calcium-dependent, large conductance, potassium (maxi-k) channel opener targeted for urge urinary incontinence

  摘要：

  A series of 1,3-diaryl 1,2,4-(4H)-triazol-5-ones was prepared and shown by electrophysiological analysis to activate a cloned maxi-K channel mSlo (or hSlo) expressed in Xenopus laevis oocytes. The effects of these structurally novel maxi-K channel openers on bladder contractile function were studied in vitro using isolated rat bladder strips pre-contracted with carbachol. Several 1,3-diaryl l,2,4-(4H)-triazol-5-one derivatives were found to be potent smooth muscle relaxants but this activity did not completely correlate with maxi-K channel opening.

  A novel approach to 2,5-disubstituted 1,3,4-oxadiazoles derivatives via a decarboxylative cyclization reaction by photoredox catalysis between commercially available α-oxocarboxylic acids and hypervalent iodine(III) reagent is described. This powerful transformation involves the coupling reaction between two different kinds of radical species and the formation of C–N and C–O bonds.

  Avoiding additives: A highly efficient and mild Pd‐catalyzed decarboxylative ortho‐acylation of azobenzenes with α‐oxocarboxylic acids was developed that provides an alternative route to acylated azo compounds. This decarboxylative acylation process was completed in the absence of any additives at ambient temperature, to afford the acylated azobenzenes in moderate to good yields (see scheme).

  K2S2O8 promoted decarboxylative alkynylation of α-keto acids and oxamic acids has been developed. This process features mild reaction conditions, a broad substrate scope, and good functional-group tolerance, therefore providing a new and efficient access to a wide range of ynones and propiolamides. Furthermore, this radical process could also be successfully applied to alkynylation of the Csp2–H bond

  The development of Minisci acylation on electron-rich pyrroles under silver-free neutral conditions has been reported featuring the regioselective monoacylation of (NH)-free pyrroles. Unlike conventional Minisci conditions, the avoidance of any acid that could result in the polymerization of pyrroles was the key to success. The umpolung reactivity of the nucleophilic acyl radical, generated in situ

  据报道，在无银中性条件下富电子吡咯的Minisci酰化反应的发展具有无（NH）吡咯的区域选择性单酰化的特征。与常规的Minisci条件不同，避免任何可能导致吡咯聚合的酸是成功的关键。由芳基乙醛酸原位产生的亲核酰基自由基的uppolung反应性可以帮助解释富电子吡咯产物形成的机理。备选地，提出了缺电子的吡咯自由基阳离子上的酰基的亲核取代。
