Enantioselective Synthesis of Sulfinamidines via Asymmetric Nitrogen Transfer from N−H Oxaziridines to Sulfenamides

Abstract

AbstractSulfinamidines are promising aza‐SIV chiral building blocks in asymmetric synthesis and drug discovery. However, no report has documented their enantioselective synthesis. Here we present an enantioselective synthesis of sulfinamidines via electrophilic amination of sulfenamides using an enantiopure N−H oxaziridine. The resulting enantiomerically enriched primary sulfinamidines are configurationally stable at 90 °C in solution and show remarkable stability against organic acids and bases under non‐aqueous conditions. We also demonstrate a one‐pot, three‐component, enantioselective synthesis of sulfinamides using N−H oxaziridine reagents.
