A New, Practical One-Pot Synthesis of Unprotected Sulfonimidamides by Transfer of Electrophilic NH to Sulfinamides

10.1002/chem.201703272

The research presents a novel and efficient method for synthesizing unprotected tertiary sulfonimidamides from tertiary sulfinamides through a one-pot transformation involving NH transfer. The key chemicals utilized in this process are (diacetoxyiodo)benzene and ammonium carbamate, which mediate the reaction under convenient conditions in methanol at room temperature. This method is notable for its high yields, broad substrate scope, and tolerance of various functional groups. The study also includes an initial exploration of the medicinal-chemistry-relevant properties of the synthesized sulfonimidamides, indicating their potential as a new and versatile pharmacophore in the life sciences. The use of commercially available reagents and the robustness of the reaction conditions highlight the practicality and safety of this synthetic approach.
