Therapeutics based on protein targeting degraders have become an extremely hot area for study in both academic and industrial arenas. The demand for rapid methods to append a glutarimide to various fragments through a C-C linkage at C3 is apparent given the sheer number of patents and publications in the area. It is striking that only two general methods were available to chemical practitioners for con-structing such compounds, both wedded to laborious polar-bond based retrosynthetic disconnections. This is due to the peculiar reactivity and physical properties of free glutarimides that render their direct crosscouplings problematic. The most inexpensive functionalized glutarimide, a-bromo derivative 1, was found to be an unwilling coupling partner in all precedented radical cross-coupling conditions. The present work illustrates how a unique Brønsted-acid assisted Nielectrocatalytic approach can tame the reactivity of 1 and render it a viable coupling partner in C-C bond formation with simple (hetero)arylhalides. While the role of the Brønsted-acid additive is speculative at the moment, it is postulated that it may serve to protect and attenuate the tendency of 1 to rapidly dehalogenate. The utility of this finding is proven by benchmarking it with state-of-the-art radical crosscoupling chemistries and implementing it to dramatically simplify the way a multitude of known PROTAC-precursors and candidates can be Methods used for comparison: prepared. The reaction is operationally trivial to conduct (insensitive to air, moisture tolerant, and conducted in an undivided cell), can be easily scaled up, and has already been field tested in a demanding pharmaceutical context.
