• Metal‐free ring opening of 5‐amino‐1, <scp> 4‐diaryl‐1 <i>H</i> </scp> ‐pyrazoles: A facile access to 2‐aryl‐3‐arylazoacrylonitriles

  2-aryl-3-arylazoacrylonitriles are synthesized while attempting the intramolecular N-arylation of 5-aminopyrazoles, using the hypervalent iodine reagent. The synthesis involves phenyl iodine diacetate-assisted ring opening of 5-aminopyrazoles at room temperature. A plausible mechanism for the formation of azoalkenes is proposed.

  A copper-catalysed intramolecular N-arylation of 5-aminopyrazoles is demonstrated for the first time. Highly substituted pyrazolo[3,4-b]indoles are synthesized. In particular, the indole core is decorated with halogens and alkyl and methoxy groups. Furthermore, a selective N-arylation of unsymmetrical diaryl bromide containing pyrazoles is exemplified, resulting in valuable pyrazolo[1,5-a]benzimidazoles

  日期：2018.7.20

  A method where an allyl alcohol is formed from a Tsuji–Trost allylation between a vinyl epoxide and an acyl containing nucleophile is described. Subsequently, a retro-Claisen condensation is utilized as a means of through-space anion relay. The anion relay results in the formation of a reactive carbanion and simultaneously activates an allylic alcohol toward intramolecular Tsuji–Trost cyclopropanation

  描述了一种方法，其中烯丙基醇由乙烯基环氧化物和含酰基亲核试剂之间的Tsuji-Trost烯丙基化反应形成。随后，逆向克莱森缩合被用作通过空间阴离子中继的手段。阴离子中继导致反应性碳负离子的形成，并同时使烯丙基醇向分子内Tsuji-Trost环丙烷化。因此，在一个锅中，使用温和且操作简单的程序，将Tsuji-Trost烯丙基化，retro-Claisen活化和Tsuji-Trost环丙烷化相结合，可从环氧乙烷中获得合成有用的乙烯基环丙烷。

• Human carbonic anhydrase inhibitory profile of mono- and bis-sulfonamides synthesized via a direct sulfochlorination of 3- and 4-(hetero)arylisoxazol-5-amine scaffolds

  Three distinct series of isoxazole-based primary mono- and bis-sulfonamides have been synthesized via direct sulfochlorination, each of them delivering nanomolar inhibitors of human carbonic anhydrase. Certain pronounced SAR trends have been established and rationalized by in silico docking. These findings expand the structure-activity knowledge base for heterocycle-containing sulfonamide carbonic anhydrase inhibitors and further validate the power of direct electrophilic sulfochlorination as a means of introducing the pharmacophoric primary sulfonamide group into structurally diverse aromatic precursors.
