Compounds, methods of use, and processes for making inhibitors of complement Factor D comprising Formula (I), or a pharmaceutically acceptable salt or composition thereof The inhibitors described herein target Factor D and inhibit or regulate the complement cascade. The inhibitors of Factor D described herein reduce the excessive activation of complement.
Fluoride-Promoted Cross-Coupling of Chloro(mono-, di-, or triphenyl)germanes with Aryl Halides in “Moist” Toluene. Multiple Transfer of the Phenyl Group from Organogermane Substrates and Comparison of the Coupling Efficiencies of Chloro(phenyl)germanes with their Corresponding Stannane and Silane Counterparts

efficient activation by fluoride to promote transfer of one, two, or three phenyl groups from the organogermanes. The corresponding chlorophenylstannanes were found to be more reactive than chlorophenylsilanes, which in turn were more effective than chlorophenylgermanes. One chloride ligand on the Ge or Si center allows efficient activation by fluoride to promote transfer of up to three aryl groups
三氯苯基-、二氯二苯基-和氯三苯基锗烷在四丁基氟化铵的甲苯中加入测量的水量。Ge 中心的一个氯化物配体允许氟化物有效活化,以促进一个、两个或三个苯基基团从有机锗烷转移。发现相应的氯苯基锡烷比氯苯基硅烷更具反应性,而氯苯基硅烷又比氯苯基锗烷更有效。Ge 或 Si 中心的一个氯化物配体允许氟化物有效活化,以促进多达三个芳基从锗烷或硅的转移。然而,Sn 中心不需要卤配体,因为在氟化物促进的与芳基卤化物的偶联过程中,四苯基锡有效地转移了多达四个苯基。19 F NMR 研究表明,氟苯基锗烷和高价锗酸盐物质的形成可能是中间体。

terminal alkynes using 1,3-diiodo-5,5,-dimethylhydantoin and HF-based reagents is disclosed. This approach is used to prepare a fluorinated tamoxifen derivative in two steps from commercially available starting materials. A facile method enabling controlled regioselective double iodofluorination of terminal alkynes is also presented.
Efficient and Practical Oxidative Bromination and Iodination of Arenes and Heteroarenes with DMSO and Hydrogen Halide: A Mild Protocol for Late-Stage Functionalization
efficient and practical system for inexpensive bromination and iodination of arenes as well as heteroarenes by using readily available dimethyl sulfoxide (DMSO) and HX (X = Br, I) reagents is reported. This mild oxidative system demonstrates a versatile protocol for the synthesis of aryl halides. HX (X = Br, I) are employed as halogenating reagents when combined with DMSO which participates in the present

Here we report the development of a versatile 3-acetylamino-2-hydroxypyridine class of ligands that promote meta-C-H arylation of anilines, heterocyclic aromatic amines, phenols, and 2-benzyl heterocycles using norbornene as a transient mediator. More than 120 examples are presented, demonstrating this ligand scaffold enables a wide substrate and coupling partner scope. Meta-C-H arylation with heterocyclic
