Description

This boronate ester features a benzo[b]thiophene moiety linked to a tetramethyl-1,3,2-dioxaborolane group, enabling efficient cross-coupling reactions. The electron-rich heterocycle enhances reactivity in palladium-catalyzed transformations, while the sterically shielded boronate ensures stability under standard conditions.

Application

2-(Benzo[b]thiophen-5-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane serves as a stable, bench-ready boron building block for Suzuki-Miyaura cross-coupling reactions. Its tetramethyl-substituted dioxaborolane moiety enhances air and moisture stability while enabling efficient coupling with aryl and heteroaryl halides. The benzo[b]thiophene core provides a versatile scaffold for pharmaceutical and materials chemistry applications, offering predictable reactivity and compatibility with diverse functional groups under standard catalytic conditions.
