Cas no 269410-24-4 (Indole-5-boronic acid, pinacol ester)

Indole-5-boronic acid pinacol ester is a stable boronic ester derivative of indole-5-boronic acid, commonly employed in Suzuki-Miyaura cross-coupling reactions. The pinacol ester group enhances the compound's stability, reducing susceptibility to protodeboronation and hydrolysis compared to its free boronic acid counterpart. This makes it particularly useful in air- and moisture-sensitive synthetic applications. The indole scaffold is a privileged structure in medicinal chemistry, and this reagent facilitates efficient functionalization at the 5-position. Its compatibility with a wide range of reaction conditions and coupling partners underscores its versatility in constructing complex heterocyclic systems for pharmaceutical and materials science research.
