4-Cyano-1-methyl-1H-pyrazole-5-boronic acid pinacol ester delivers a stable, bench-tolerant boronate handle for Suzuki-Miyaura couplings. The electron-deficient pyrazole core enhances reactivity, while the pinacol ester protects the boronic acid functionality. This compound integrates seamlessly into complex molecule synthesis, enabling efficient C–C bond formation under mild conditions.
4-Cyano-1-methyl-1H-pyrazole-5-boronic acid pinacol ester serves as a versatile boronate building block for Suzuki-Miyaura cross-coupling reactions. The pinacol ester enhances stability and ease of handling, while the cyano and methyl groups provide orthogonal functionalization potential. It reacts reliably with aryl and vinyl halides under mild conditions, enabling efficient construction of complex pyrazole-containing scaffolds relevant to medicinal chemistry and materials science.
