Ureas and sulfoximines are relevant as natural products pharmaceuticals. The fusion of these two frameworks results in (sulfoxylidene)ureas. Herein, we present a convenient method to access such compounds from NH-sulfoximines dioxazolones. reactions assisted by 2,2,2-trifluoroethanol (TFE), yielding the desired moderate good yields under mild reaction conditions. process, which involves Curtius rearrangement, is characterized its simplicity absence any additional activator rendering it appealing for applications medicinal chemistry.

Comprehensive Summary Herein, we developed a tertiary amine‐catalyzed stereoretentive multi‐component cascade reaction featuring an amidation/[4 + 1] annulation/decarboxylation/Curtius rearrangement/[2 n ] annulation sequence. This metal‐free and step‐economic method provided broad range of cyclic ureas/urethanes in green solvent under mild conditions without employing explosive toxic reagents. Importantly, this generated isocyanates situ catalytic via decarboxylation/Curtius rearrangement process dioxazolones.
