A synthesis of 5-hydroxycoumarans, 6-hydroxychromanes and their dodecylthiomethylsubstituted derivatives was accomplished based on methylphenols through the intermediate preparation of 2-allyl-4-alkoxyphenols. The sulfur-containing compounds synthesized were shown to be highly efficient as inhibitors of autooxidation of methyl oleate.

A simple and efficient synthetic protocol for alkylthiomethylation of quercetin was proposed. New sulfur-containing quercetin derivatives were obtained by the reaction of this flavonoid with (N,N-diethylaminomethyl)dodecyl sulfide.

Reactions of 2,6-dialkylphenols with N-(N′,N′-diethylaminomethyl)phthalimide gave the corresponding 4-phthaloylmethylphenols, in which the phthaloyl group can be replaced by an alkylsulfanyl substituent via reactions with thiols. Phthaloylmethylphenols containing the tert-butyl groups that are ortho to the OH group can undergo acid-catalyzed de-tert-butylation.
