environmentally‐friendly N‐triazinylammonium family of sulfonates, has been found to be a very effective coupling reagent for the synthesis of amides, esters and peptides in solution. This study confirms the usefulness of DMT/NMM/TsO− for peptidesynthesis in solution, starting from Z‐, Fmoc‐, and Boc‐protected substrates as well as unnatural building blocks. Peptidesynthesis with DMT/NMM/TsO− produced

Regioselective C–H amination of simple arenes is highly desirable, but accessing meta-sites of ubiquitous arenes has proven challenging due to the lack of both electronic and spatial preference. This study demonstrates the successful use of various privileged nitrogen-containing functionalities found in pharmaceutical compounds to direct meta-C–H amination of arenes, overcoming the long-standing requirement
