Description générale

Sulfoxonium ylides are highly stable carbene precursors, serving as a safer alternative to diazo compounds as they that do not generate gases as byproducts. Sulfoxonium ylides have been shown to be effective in a wide array of transition metal catalyzed C-H functionalization and coupling reactions.

A rhodium-catalyzed annulation between ethyl benzimidates and α- aroyl sulfur ylides was developed, affording a series of pyrano[4,3,2-ij]isoquinoline derivatives in moderate to good yields with good functional group compatibility. The procedure featured dual ortho-C-H functionalization and dual cyclization in one

A ruthenium-catalysed cross-olefination of diazo compounds and sulfoxonium ylides is presented. Our reaction design exploits the intrinsic difference in reactivity of diazo compounds and sulfoxonium ylides as both carbene precursors and nucleophiles, which results in a highly selective reaction.

Rh(III)-catalyzed cascade C-H activation of benzoylacetonitriles and annulation with sulfoxonium ylides was realized, leading to selective synthesis of naphthols, 2,3-dihydronaphtho[1,8- bc]pyrans, and naphtho[1,8- bc]pyrans. This step-economic reaction proceeded efficiently under mild and redox-neutral conditions via multiple C-H activations.
