摘要:
Disclosed are compounds of formula I and II and pharmaceutically acceptable salts thereof. Also disclosed are methods of treating a neurodegenerative disorder, an inflammatory disease, an autoimmune disease, an ophthalmic disease or a metabolic disorder using the compounds disclosed herein.
We have developed an efficient Pd‐catalyzed directed C—H bromination protocol, in which dimethyl sulfoxide (DMSO) is employed as oxidant with hydrobromic acid aqueous solution (HBr(aq)) as bromide source. The DMSO/HBr(aq) system, which is novelly and efficiently utilized in transition‐metal catalyzed C—H activation, illustrates its practicability by the operational simplicity, inexpensive and readily
In this work, we report the first use of a salen-based hypercrosslinked polymer-supportedPdcatalyst to carry out C-H halogenation. This catalyst can effectively catalyze C-H bromination and chlorination even better than its homogeneous counterpart Pd(OAc)2. It also showed excellent reusability without loss of catalytic activity for ten cycles. A broad substrate scope was explored and moderate to

sequential borylation and aerobic oxidative copper catalysis, and the corresponding aryl halides, sulfones, azides and arylamines were obtained in good yields. The protocol uses cheap and readily available boron tribromide (BBr3) as the borylating reagent, and inorganic salts (potassium iodide, ammonium bromide, sodium alkylsulfinates, sodium azide) as the functional group sources. This method makes
