as alkoxy quinolines were halogenated at the C5-position via remote functionalization for the first time. This methodology provides a highly economical route to halogenatedquinolines with excellent functional group tolerance, thus providing a good complement to existing remote functionalization methods of quinolin-8-amide derivatives and broadening the field of remote functionalization. The utility

Provided herein are Sulfonamide compounds of Formula I: and pharmaceutically acceptable salts, tautomers, isotopologues, and stereoisomers thereof, wherein R1, R2, R, A, m, n, and p are as defined herein, compositions comprising an effective amount of a Sulfonamide Compound, and methods for treating or preventing animal and human filarial worm infections and diseases.
Disclosed are sulfonamidoquinoline compounds, as well as pharmaceutical compositions and methods of use. One embodiment is a compound having the structure
and pharmaceutically acceptable salts, prodrugs and N-oxides thereof (and solvates and hydrates thereof), wherein R1, R2, R3 and R4 are as described herein. In certain embodiments, a compound disclosed herein inhibits ubiquitination, and can be used to treat disease by blocking the degradation of tumor suppressors.
An efficient and convenient method for remote C5 halogenation of 8-aminoquinoline derivatives was developed in continuous flow at room temperature. This method employed inexpensive 1,3-dibromo-5,5-dimethylhydantoin (DBDMH) and 1,3-dichlro-5,5-dimethylhydantoin (DCDMH) as halogenation reagents and visible light to catalyze the reaction. The reaction is scalable to gram-scale and proceeded with air and moisture tolerance, good functional group compatibility, and outstanding site selectivity, providing a new pathway for C5 halogenation of 8-aminoquinolines.
