A practical and environmentally benign electrochemical oxidation of thioethers and thiols in a commercially-available continuous-flow microreactor is presented. Water is used as the source of oxygen to enable the oxidation process. The oxidation reaction utilizes the same reagents in all scenarios and the selectivity is solely governed by the applied potential. The procedure exhibits a broad scope

offer advantages over existing cysteine alkylation reagents, including accelerated reaction rates, improved stability, and robust ionization for mass spectrometry applications. Overall, heteroaromatic sulfones provide modular tunability, shifted chromatographic elution times, and superior in-cell cysteine profiling for in-depth proteome-wide analysis and covalent ligand discovery.
Provided herein are heterocyclic compounds for treatment of CSF1R, FLT3, KIT, and/or PDGFRβ kinase mediated diseases. Also provided are pharmaceutical compositions comprising the compounds and methods of using the compounds and compositions.

Treatment of 2-methylsulfinylbenzazoles with triflic anhydride in the presence of phenols yields the corresponding 4-(p-hydroxyphenyl)-2-methylsulfanylbenzazoles. This regioselective dehydrative C–H/C–H coupling arylation represents a rare example of functionalizations on the benzene rings of benzo-fused azoles.
