Carbene-mediated stereoselective olefination of vinyl sulfoxonium ylides with diazo compounds and acetals
The development of stereoselective olefination using sulfur ylide-derived vinyl carbenes with diazo esters and acetals is reported. Both reactions proceed through nucleophilic addition to electrophiles at the γ-position of an in situ-generated 2-alkoxy furan intermediate. The synthetic utility of the developed method is demonstrated by the total synthesis of rubrolide E. Detailed mechanistic investigations and quantum chemical calculations provide insight into the reaction mechanism.
