Within heteroarene platforms, DAAS-Na allows for the direct introduction of a difluoroalkyl chain carrying an azide group, which is designed for the purpose of bioconjugation. Through a Huisgen cycloaddition (a "click" reaction), the azide moiety can then be reacted with a terminal alkyne that is bound to a functional molecule such as biomacromolecules. This effectively allows for a covalent linkage between a heteroarene and any target molecule, for example, between a heteroarene-containing drug and an antibody. This reagent was developed by the Baran Group and is one of several reagents for the direct alkylation of heterocycles.
