[reaction: see text] A new intermolecular metathesis between a variety of alkynes and alkyl enol ethers is described. The best results were obtained with the second generation Grubbs' precatalysts. The reaction occurred with a high degree of regioselectivity and provided electron-rich dienes, which underwent a variety of [4 + 2] cycloadditions.
