General description

Application

Protected boronic acid with methylimindodiacetic acid (MIDA) that does not react under standard Suzuki-Miyuara coupling conditions, allowing for selective and iterative cross-coupling sequences. The MIDA boronate also provides prolonged shelf life and stability to typically unstable boronic acid derivatives.
