一般描述

(E)-1-Pentene-1,2-diboronic acid bis(pinacol) ester is an alkenyl boronate ester that can be utilized for Suzuki-Miyaura cross-coupling reaction. Boronate esters are air- and chromatography-stable.

应用

(E)-1-Pentene-1,2-diboronic acid bis(pinacol) ester can be used as a reactant in the stereoselective synthesis of γ-boryl substituted homoallylic alcohols by reacting with aromatic aldehydes via Ru-catalyzed double bond transposition reaction.[1]
