Description

1-Ethyl-3-methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole is a bench-stable boronate reagent featuring a pyrazole core with orthogonal functional handles. The tetramethyl-substituted dioxaborolane moiety enables efficient Suzuki-Miyaura coupling under mild conditions. This sterically protected boronate integrates seamlessly into complex molecular architectures, delivering high chemoselectivity and stability during synthesis workflows.

Application

1-Ethyl-3-methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole serves as a stable, bench-ready boronate building block for Suzuki-Miyaura cross-coupling reactions. Its pyrazole core provides moderate electron-withdrawing character and enhanced solubility, while the tetramethyl-substituted dioxaborolane moiety ensures high reactivity and stability under ambient conditions. This compound enables efficient construction of biaryl and heteroaryl architectures in medicinal chemistry and materials synthesis workflows.
