Used in organic synthesis as a chiral building block for the preparation of complex natural products and pharmaceuticals. Its protected hydroxyl group and rigid cyclic structure make it valuable in asymmetric synthesis, particularly in the development of bioactive molecules where stereochemistry is critical. Commonly employed in the construction of pyrrolidine-based scaffolds found in neuroactive compounds and enzyme inhibitors. The silyl protecting group allows for selective deprotection and further functionalization under mild conditions, enabling stepwise elaboration in multi-step syntheses.
