The Ylide Dance: Base-Induced Furan Synthesis via Formal [3+2] Annulation of Phenacyl- and Alkenyl Sulfonium Salts
{{output}}
A methodology for the synthesis of substituted furans via an "ylide dance" sequence has been developed. The reaction involves phenacyl sulfonium salts and alkenyl- or propargyl sulfonium salts under basic conditions. The key feature is a stepwise evolution w... ...
