Metal-free N-acylation of sulfoximines with carboxylic acids via N-chlorophthalimide/triphenylphosphine-mediated activation.
Herein, we describe a metal-free N-acylation of sulfoximines mediated by an N-chlorophthalimide/triphenylphosphine (NCP/PPh3) system. The transformation proceeds under mild reaction conditions and provides efficient access to structurally diverse N-acyl sulfoximines in good yields. The protocol exhibits a broad substra...
