Novel compounds which are 2,6-di-t-butylphenols substituted in the 4 position by an alkoxy or benzyloxy group or a benzylthio group, which alkoxy or benzyloxy group is directly substituted by a tetrazole ring, and which benzylthio group is directly substituted by carboxy or tetrazolyl are useful as inhibitors of leukotriene biosynthesis and as antiallergic agents. Synthetic intermediates for preparing such compounds are also described.
