for borylation of alkylbromides and iodides to alkyl boronic esters under transition metal- and light-free conditions. A series of substrates with a wide range of functional groups were effectively transformed into the borylation products in moderate to good yields. Mechanistic studies, including radical clock experiments and DFT calculations, gave detailed insight into the radical borylation process

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.

a peripheral imidazole group. The imidazole ring posed some problems in the click chemistry putatively due to Cu(II) coordination, but Boc protection of the imidazole and removal of oxygen from the reaction mixture provided effective strategies. Pharmacological studies revealed two monosubstituted imidazoles (6h,p) with <10 nM H4R affinities and >10-fold H4R/H3R selectivity. Both compounds possess
组胺H 3(H 3 R)和H 4(H 4 R)受体引起了药物化学界的极大兴趣。鉴于它们相对较高的同源性,但治疗前景却大相径庭,因此对两种受体的配体选择性至关重要。我们使用具有[1,2,3]三唑核心的配体询问H 4 R / H 3 R的选择性。Cu(I)辅助的“点击化学”被用来组装各种[1,2,3]三唑化合物(6a - w和7a - f),许多含有外围咪唑基团。咪唑环可能由于Cu(II)配位而在点击化学中造成了一些问题,但是咪唑的Boc保护和从反应混合物中除去氧气提供了有效的策略。药理研究表明,两种单取代的咪唑(6h,p)的亲和力<10 nM H 4 R和H 4 R / H 3 R选择性> 10倍。两种化合物均具有环烷基甲基,并且似乎靶向H 4中的亲脂性口袋R具有很高的空间精度。[1,2,3]三唑支架的使用进一步证明了以下概念,即间隔区长度或外围基团的简单改变可以逆转对H 3 R的选择性。提
