Facile synthesis of 3-methylbenzene oxide and 1-methylbenzene oxide, and 1H-NMR data for Diels-Alder adducts of three methylbenzene oxides with 4-phenyl-1,2,4-triazoline-3,5-dione

Article abstract of DOI:10.1248/cpb.41.2106

Diels-Alder reaction of methyl-substituted 1,3-butadienes (1) with 1,2-dibromoethylene gave dibromomethylcyclohexenes (2), which were subjected to epoxidation, followed by dehydrobromination of the resultant dibromo oxides (3) to afford 3-methylbenzene oxide (4a) and 1-methylbenzene oxide (4b). However, 4-methylbenzene oxide (4c) could not be obtained in this way.
