[图解]描述了一种新的分子间异构化反应，该反应发生在不同的炔烃和烷基烯醇醚之间。第二代格拉布斯预催化剂的催化效果最好。该反应具有很高的区域选择性，并提供了富含电子的二烯，这些二烯经历了各种[4+2]环加成反应。
[GRAPHICS]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.
