A rapid construction of new boron heterocycles and evaluation of photophysical properties of iminoboronates

Abstract

A green and efficient method for the synthesis of oxadiazaborole, dioxazaborinine, and oxadiazaborinine from the reactions of phenylboronic acid with amidoxime, α-hydroxyl oxime and α-hydroxyl hydrazone, respectively, is described. The...

Transient hydroboration and hydroalumination of activated azo-species: avenues to NBO and NAlO-heterobicycles

“…1–3 Initially studied as an academic interest, 4 such species have found applications in a range of fields including in materials 1,5–8 and synthesis, 9 as well as in imaging 10,11 and potential pharmaceutical reagents (Scheme 1). 12–17 Among the various heterocyclic boron derivatives, species in which boron is chelated to O and N donors, so-called BON heterocycles, have garnered particular attention as such heterocycles exhibit antimicrobial and anticancer activity. 18 One such heterocycle is the benzoxaborole ring, which has been recognized as a privileged pharmacophore as it exhibits activity for a range of therapeutic targets.…”

A rapid construction of 1,3,2-benzodiazaborininones [R–B(aam)] from boronic acids and anthranilamides

“…In our previous work, R–B(dan), oxdiazobium compound, dioxazobium compound and oxdiazobium compound were synthesized by a simple method 43,44 (Fig. 4).…”
