Article abstract of DOI:10.1021/ja00196a041

The base-catalyzed intramolecular cycloaddition reactions (t-BuOK, t-BuOH, 83 deg C) of variously substituted propargyl 3-vinyl-2-cyclohexenyl ethers have been investigated.The reaction proceeded smoothly via the initial isomerization to the corresponding
