Described herein are compounds, methods of making such compounds, pharmaceutical compositions and medicaments containing such compounds, and methods of using such compounds to treat or prevent diseases or disorders associated with a defect in glyoxylate metabolism, for example a disease or disorder associated with the enzyme glycolate oxidase (GO) or alterations in oxalate metabolism. Such diseases or disorders include, for example, disorders of glyoxylate metabolism, including primary hyperoxaluria, that are associated with production of excessive amounts of oxalate.

the activation of bonds with high bond dissociation energy and to substrates with high reduction potentials. Herein, we introduce a novel photocatalytic strategy for the activation of inert substituted arenes for aryl borylation by using thiolate as a catalyst. This catalytic system exhibits strong reducing ability and engages non-activated Caryl–F, Caryl–X, Caryl–O, Caryl–N, and Caryl–S bonds in productive

studies suggest that the reaction proceeds via an SRN1mechanism involving a single-electron-transfer (SET) process and not via the typical SNAr mechanism. This method differs from the previously reported nickel/copper-cocatalyzed system in terms of scope of the substrate and has exhibited good scalability. Double and triple ipso-borylations of several di- and trifluoroarenes have been also achieved
本位fluoroarenes的-Borylation已经使用空气稳定的铜配合物作为催化剂来实现的。机理研究表明,反应是通过涉及单电子转移(SET)过程的S RN 1机理而不是通过典型的S N Ar机理进行的。该方法在基材范围方面与先前报道的镍/铜共催化体系不同,并且具有良好的可扩展性。双重和三重IPSO几个二和trifluoroarenes的-borylations也已被有效地实现,从而提高了该方法的综合效用。
