Product Overview

CAS 1802149-87-6 5-(5,5-Dimethyl-1,3,2-dioxaborinan-2-yl)-3-methylbenzo[d]oxazol-2(3H)-one (also named 2(3H)-Benzoxazolone, 5-(5,5-dimethyl-1,3,2-dioxaborinan-2-yl)-3-methyl-).

Applications

Organoboron Cross-Coupling Reagent: Features a neopentyl glycol ester protected boronic acid (neopentyl boronate ester) attached to a 3-methyl-2-benzoxazolinone core.

Suzuki-Miyaura Partner: The cyclic boronate ester provides enhanced stability and air/moisture resistance compared to free boronic acids, making it an excellent coupling partner for palladium-catalyzed Suzuki-Miyaura reactions to construct functionalized biaryl systems.

Pharmaceutical Intermediate: Serves as a key synthetic intermediate and reference standard/impurity (e.g., Brensocatib Impurity-16) in the discovery and quality control of small-molecule therapeutics targeting inflammatory and metabolic pathways.
