Used as a key intermediate in organic synthesis, particularly in the preparation of nitrogen-containing compounds. It serves as a protected amine reagent in multi-step synthesis, offering stability under various reaction conditions while allowing selective deprotection when needed. Commonly employed in pharmaceutical manufacturing for building complex amine architectures, especially in protease inhibitors and other bioactive molecules. Its allyl groups enable further functionalization via cross-coupling or olefin transformation reactions, making it valuable in medicinal chemistry and process development.
