Used in advanced organic synthesis, particularly in the preparation of vitamin D analogs and related complex natural products. Its highly functionalized structure, featuring a steroid-like core with protected hydroxyl groups and multiple chiral centers, makes it a valuable intermediate in stereoselective reactions. Commonly employed in the development of pharmaceuticals targeting cholesterol metabolism, such as vitamin D derivatives for conditions like psoriasis and hyperparathyroidism, as well as anti-inflammatory agents. The tert-butyldimethylsilyloxy protections enable selective transformations, allowing precise control over stereochemistry and functional group compatibility in multi-step syntheses.
