Description

Application

Quinoxaline-6-boronic acid pinacol ester is a common reactant of a Suzuki coupling reaction that can be used:

• To prepare quinoxalin based PI3Kδ inhibitors.
• As a substrate in the Cu(II) catalyzed [¹¹C]-radiocyanation of arylboronic acids.
• To prepare 6-quinoxaline boronic acid, which is used as a substrate in the silver-mediated fluorination of boronic acids.
