3, 4, 5, 6, -Tetrahydro-7-hydroxy-2-methyl-9-alkyl-2, 6-methano-2H-1-benzoxocins are readily prepared by baron trifluoride etherate-catalyzed cyclization of resorcinols with cyclic allylic alcohol.

The alkylation of resorcinol with cyclic allylic alcohol in non-aqueous acid medium gives intermolecular Friedel-Craft compounds. The products are primary alkylation products. The likage always occurs between carbon 3 of cyclic allylic alcohol and the position 2, 4, 5 or 6 of the resorcinol.
