The straightforward synthesis of a highly biologically active 3-piperazine-bisbenzoxaborole and its fluorine analog has been described. The obtained bisbenzoxaboroles have been used in the synthesis of their phenylboronic acids analogs. One diboronic acid has been also isolated as hydrochloride salt as well as its methyl monoester. All the described compounds display unique molecular architectures, which have been determined by X-ray measurements.
