  Palladium-Catalyzed C−H Arylation of 2,5-Substituted Pyrroles

  摘要：

  The palladium-catalyzed direct arylation of 2,5-substituted pyrrole derivatives with diaryliodonium salts to generate tri-, tetra-, and penta-substituted pyrrole products is described. The scope and limitations of these transformations are also reported.

  of nitroalkenes with enol ethers followed by reductive ring contraction of the resulting cyclic nitronates provides a new access to polysubstituted NH pyrroles. Unlike conventional synthetic routes (Barton-Zard, Knorr, Hantzsch, Van Leusen pyrrole syntheses), this strategy affords NH pyrroles that do not necessarily contain a EWG group in the ring.

  硝基烯烃与烯醇醚的[4+2]-环加成，随后所得环状硝基化合物的还原环收缩提供了获得多取代NH吡咯的新途径。与传统的合成路线（Barton-Zard、Knorr、Hantzsch、Van Leusen 吡咯合成）不同，该策略提供的 NH 吡咯在环中不一定包含 EWG 基团。

  Proteinopathies result from the proteasome not acting efficiently enough to eliminate harmful proteins and prevent the formation of the pathogenic aggregates. As described herein, inhibition of proteasome-associated deubiquitinase Usp 14 results in increased proteasome efficiency. The present invention therefore provides novel compositions and methods for inhibition of Uspl4, enhancement of proteasome activity and treatment of proteinopathies.
