Description

This boronate-functionalized pyrazolo[5,1-b][1,3]oxazine integrates seamlessly into cross-coupling reactions under mild conditions. The tetramethylboronate moiety enables efficient palladium-catalyzed transformations, while the dihydrooxazine scaffold provides enhanced stability and solubility in organic media.

Application

3-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-6,7-dihydro-5H-pyrazolo[5,1-b][1,3]oxazine serves as a versatile boronate building block for Suzuki-Miyaura cross-coupling reactions. The tetramethylboronate group enables efficient palladium-catalyzed coupling with aryl and vinyl halides under mild conditions. The pyrazolo[5,1-b][1,3]oxazine core provides structural rigidity and functional group tolerance, enhancing utility in medicinal chemistry and API synthesis. Bench-stable and readily purified by flash chromatography, it facilitates scalable construction of complex heterocyclic scaffolds.
