        Reaction Between 1,3-Dicarbonyl-Containing CH Acids and Dialkyl Acetylenedicarboxylates in the Presence of Silica Gel in Solvent-Free Conditions: An Efficient Method for the Synthesis of Electron-Poor Alkenes and Pyranes      

A two-component condensation reaction between a 1,3-dicarbonylcontaining CH acid and an electron-poor acetylenic ester efficiently provides fully substituted electron-poor alkenes and pyranes in a one-pot reaction in the presence of silica gel in solvent-free conditions.
