Electrochemical N-acylation and N-α-ketoacylation of sulfoximines via the selective decarboxylation and dehydration of α-ketoacids

Green Chem., 2023, Advance Article
DOI: 10.1039/D3GC02674D, Paper
Chen Kang, Mingzhe Li, Wenxiu Huang, Shoucai Wang, Mengyu Peng, Longqiang Zhao, Guangbin Jiang, Fanghua Ji
We describe an electrochemical N-acylation and N-α-ketoacylation of sulfoximines via the selective decarboxylation and dehydration of α-ketoacids using electricity as a “traceless” oxidant and α-ketoacid as a selective “acyl” or “α-ketoacyl” source.
