The development of a short, simple, and efficient synthesis of amino‐ and hydroxymethyl‐substituted benzoxaboroles is described. The key step was the early stage incorporation of the boron by the borylation of an aniline. The formed boronates were then elaborated to the final products in two additional steps, in good yields.
