Herein, we disclose a transition-metal-free reaction system that enables α-cyanation of sulfonamides through C–H bond cleavage for the preparation of α-amino nitriles, including difficult-to-access all-alkyl α-tertiary scaffolds. More than 50 substrate examples prove a wide functional group tolerance. Additionally, its synthetic practicality is highlighted by gram-scalability and the late-stage modification
site‐selective α‐functionalization of sulfonylamide derivatives through the in‐situ generation of imine intermediates. The N−F sulfonylamides, which could facilitate the elimination to generate imines, are coupled with TBACN to efficiently and mildly afford α‐amino cyanides. Comparing with Strecker reaction, this transformation offers a complementary strategy to efficiently construct α‐amino cyanides
