摘要

Rearrangement of β-ionone epoxide with aqueous formic acid gave 1, 2-dihydro-1, 1, 6- trimethylnaphthalen (2), 1-(1, 2, 2-trimethylcyclopent-1-yl)-2-penten-1, 4-dione (3), 4-(5, 5- dimethyl-2-acetyl-1-cyclopenten-1-yl)-2-butanone (5), 4-(1, 3, 3-trimethyl-2-cyclohexanon-1- yl)-3-buten-2-one (6), 4-(2, 3, 6-trimethylphenyl)-2-butanone (7) and 6, 6-dimethyl-2, 5-10- undecatrione (8). NMR assignments are made for each compound while a computer ...
