boroxole motif traditionally relies on a 3-step process and the use of n-butyl lithium that can limit substrate scope. Herein during our exploration toward novel RORγ inhibitors, we identified a convenient one-pot preparation of the motif in good yields with good substrate scope.

Organoboroncompounds are valuable molecules of increasing interest in organic synthesis, catalysis, biology and medicine. Among them, benzoxaboroles emerged as promising building blocks for numerous research programs. In this letter, we communicate the development of new conditions for the one‐pot benzoxaborole synthesis by SiliaCat DPP−Pd catalysis using diboronicacid as the boron source. This low
