Synthesis of γ-Carbonyl Aliphatic Sulfoxonium Salts via Site-Selective Ring Opening of In Situ Formed 2-Sulfoxonium Cyclobutanone
{{output}}
We report herein a Rh-catalyzed tandem reaction between a pivaloyl-substituted sulfoxonium-iodonium ylide and diverse nucleophiles, enabling the efficient synthesis of γ-sulfoxonium carbonyl compounds, which were previously inaccessible. This transformation p... ...
