Used as a key intermediate in organic synthesis, particularly in the construction of complex natural products and pharmaceuticals. Its silyl-protected alcohol group allows selective deprotection under mild conditions, enabling sequential functionalization. The terminal alkene moiety serves as a handle for further transformations such as cross-metathesis or hydroboration, while the ester group can be reduced or hydrolyzed to access alcohols or carboxylic acids. Commonly employed in multi-step syntheses where orthogonal protection and controlled reactivity are required.
