Sulfinamide is a functional group in organic chemistry containing a sulfur-oxygen double bond and a sulfur-nitrogen single bond. Sulfinamides are amides of sulfinic acid.
Chiral sulfinamides such as tert-butanesulfinamide, p-toluenesulfinamide[1][2] and 2,4,6-trimethylbenzenesulfinamide[3] are relevant to asymmetric synthesis.
