For the first time, dehydroabietane-derived alcohols containing an OH group at the C-7 position were used to produce thioacetates by direct ZnCl2-catalyzed substitution of the hydroxyl group. Thioacetates obtained were found to give the corresponding disulfides when treated with MeONa in the presence of atmospheric oxygen with no observation of any thiol formation. In addition, the ability of diol
