Used in organic synthesis as a protective group for amines, particularly in the preparation of complex molecules. It is valuable in medicinal chemistry for the development of indole-based compounds, which are often explored for their biological activity. The tert-butyl ester group provides stability during reactions, allowing for selective modifications of the indole core. This compound is also employed in the synthesis of pharmaceutical intermediates, aiding in the creation of potential drug candidates targeting various diseases. Its application extends to peptide chemistry, where it helps in the controlled assembly of amino acids.
