The first Bronsted acidcatalyzed enantioselective addition of thiols to the in situ generated ortho-quinone methides (o-QMs) is described. Complementary to the chiral amine catalyzed approach, the present reaction employs a chiral phosphoric acid as the catalyst. The readily available o-hydroxybenzyl alcohols serve as the atom-economical precursors of o-QMs to react with tritylthiol with moderate
