This chemical is primarily utilized in organic synthesis as a versatile building block for constructing complex molecular structures. It is particularly valuable in the development of pharmaceuticals and bioactive compounds due to its cyclopropyl and ethynyl functional groups, which enable diverse chemical transformations. The tert-butyl carbamate moiety serves as a protective group for amines, allowing selective reactions to occur without interference. Its application is prominent in the synthesis of small molecule drugs, where it aids in creating intermediates with specific stereochemistry and functional group compatibility. Additionally, it is used in the preparation of cyclopropylacetylene derivatives, which are key components in materials science and medicinal chemistry research.
