Widely used in Suzuki-Miyaura cross-coupling reactions, this compound serves as a key intermediate in the synthesis of complex indole derivatives. Its boronate ester group enables efficient carbon-carbon bond formation under mild conditions, making it valuable in pharmaceutical and agrochemical research. The tert-butyl carbamate (Boc) protection on the indole nitrogen ensures stability during reaction sequences and allows for selective deprotection when needed. This dual functionality supports the construction of highly substituted indole scaffolds found in bioactive molecules and drug candidates.
