摘要

A series of substituted 3-cyclohexenols was prepared and subjected to the iodomethylzinc iodide methylenation reaction. Competitive kinetics establish that, in contrast to the allylic 2- cyclohexenols, the homoallylic 3-cyclohexenols react through the axial hydroxyl conformer. The compounds examined (!-%, I) are 3-cyclohexenol (l, O), cis-6-methyl-3-cyclohexenol (5.2), 1-methyl-3-cyclohexenol (4.0), trans-6-methyl-3-cyclohexenol (2.6), trans-1, 4, 5, 6, 7 ...
