Used in advanced organic synthesis, particularly in the preparation of complex natural products and pharmaceutical intermediates. Its highly functionalized structure, with multiple stereocenters and protected hydroxyl groups, makes it a valuable chiral building block for constructing bioactive molecules, especially in the development of vitamin D analogs and other steroid-like compounds. The tert-butyldimethylsilyl (TBS) protecting groups allow selective deprotection and further derivatization, enabling stepwise synthesis in multi-step reaction sequences. Commonly employed in research settings for total synthesis of terpenoids and related polycyclic compounds.
