一般描述

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.

The synthesis of bridgehead N-fused [5,6]-bicyclic heterocycles via rhodium(III)-catalyzed C-H functionalization of C-alkenyl azoles with sulfoxonium ylides is disclosed. Reactions proceeded in good to high yields for a range of aryl, heteroaryl and alkyl sulfoxonium ylides. In addition, 2-alkenyl imidazoles
