Cu-Catalysed Mild Synthesis of N-Imidoyl and N-Oxoimidoyl Sulfonimidamides through the Three-Component Coupling of Sulfonimidamides, Azides, and Alkynes

Abstract

Hitherto unknown N-imidoyl sulfonimidamides have been synthesized by a Cu-catalysed mild one-pot multicomponent reaction of sulfonimidamides, azides, and alkynes in THF at room temperature under air in moderate to good yield. Fur-thermore, in the presence of molecular oxygen, the N-imidoyl sulfonimidamides were further oxidized to give N-oxoimidoyl sulfonimidamides.
