Used as a chiral catalyst in asymmetric synthesis, particularly in enantioselective alkylation and aldol reactions. Its boranuide structure enables selective transfer of hydrides, making it valuable in pharmaceutical intermediates synthesis where stereochemistry control is critical. Commonly applied in the preparation of optically active compounds, including precursors to nonsteroidal anti-inflammatory drugs (NSAIDs) and other bioactive molecules. The ethoxycarbonyl group enhances solubility and stability in organic solvents, supporting its use in homogeneous catalytic systems.
