α-Tertiary amines are essential building blocks for pharmaceuticals, agrochemicals, and specialty chemicals, forming the core of kinase inhibitors, antiretrovirals, and receptor antagonists. As drug discovery demands more novel chemical entities, the industry urgently needs efficient, scalable ways to synthesize these complex nitrogen frameworks. Without reliable production methods, medicinal chemistry advancement and new therapeutic development remain constrained.
This technology offers a streamlined, two step route to α-tertiary amines using stable organoborons instead of hazardous organometallic reagents. An oxidative radical coupling forms new carbon–carbon bonds, followed by zinc-mediated cleavage to deliver the final amine. Unlike traditional methods requiring air- and moisture-free conditions and toxic azide reagents, this process runs safely in water under mild conditions. The result is a modular, water compatible synthesis that simplifies manufacturing, reduces hazards, and expands access to complex amine frameworks.
