The present invention provides a compound of Formula (I), and pharmaceutical compositions comprising one or more said compounds, and methods for using said compounds for treating or preventing one or more disease states that could benefit from inhibition of plasma kallikrein, including hereditary angioedema, uveitis, posterior uveitis, wet age related macular edema, diabetic macular edema, diabetic retinopathy and retinal vein occlusion. The compounds are selective inhibitors of plasma kallikrein.
synthesized, in which the aluminum atom played as a proximal Lewisacidic site. Based on their structural analysis, aluminabenzene ligand could coordinate to Rh and Ir as a η5-pentadienyl ligand. The Lewisacidiccharacter of aluminum atom in aluminabenzene ligand was confirmed by treatment with 4-dimethylaminopyridine to form the corresponding Lewis acid-base complexes. In addition, the α-selective C-H borylation
合成了铝苯-铑和-铱配合物,其中铝原子作为近端路易斯酸性位点。根据它们的结构分析,氧化铝苯配体可以作为 η5-戊二烯基配体与 Rh 和 Ir 配位。通过用4-二甲氨基吡啶处理形成相应的路易斯酸碱配合物,证实了氧化铝苯配体中铝原子的路易斯酸性特征。此外,还证明了三乙胺与氧化铝苯连接的铱催化剂的 α-选择性 CH 硼酰化。

trifluoroborates with aryl bromides using Ni/photoredox dual catalysis has been developed. This C(sp2)–C(sp3) cross-coupling provides access to pharmaceutically relevant chiral N-benzylic heterocycles in good to excellent enantioselectivity when bioxazolines (BiOX) are used as the chiral ligand. High-throughput experimentation significantly streamlined reaction development by identifying BiOX ligands for further

Alkylboronic pinacol esters (APEs) are highly versatile reagents in organic synthesis. However, the direct generation of alkyl radicals from commonly used, bench-stable APEs has not been well explored. In this communication, alkyl radical generation from APEs through reaction with aminyl radicals is reported. The aminyl radicals are readily generated by visible-light-induced homolytic cleavage of the
烷基硼频哪醇酯 (APE) 是有机合成中用途广泛的试剂。然而,从常用的、实验室稳定的 APEs 直接产生烷基自由基的方法尚未得到很好的探索。在此通讯中,报道了 APE 通过与氨基自由基反应生成烷基自由基。氨基自由基很容易通过可见光诱导的 N-亚硝胺中 N-N 键的均裂裂解产生,而 C 自由基的产生通过硼的核均裂取代发生。作为一项应用,提出了在温和条件下烯烃与 APE 和N-亚硝胺的高效光化学自由基烷基肟化反应。范围广泛的一级、二级和三级 APEs 参与了这种很容易扩大规模的转变。
