Abstract: In the present study, the Bi(OTf)3 catalyzed thia-Michael addition to ortho-quinone methides for the synthesis of ortho-hydroxybenzyl thioethers with 2-[hydroxy(phenyl)methyl phenols and vinyl thioethers in 1,2-dichloroethane was developed. The reaction could be achieved at 30 ℃ for 3 h and the products were obtained in moderate to good yields (78%~88%). The prominent features of the present strategy are good chemical selectivity and with wide substrate scope. For 2-hydroxy(phenyl)methyl phenols, electron-withdrawing groups and electron-donating groups on aromatic rings could react soothly to obtain corresponding products. Also, the reaction could be achieved with phenyl vinyl thioether and ethyl vinyl thioether. Furthermore, the reaction could be scaled up to multigram scale.

Key words: ortho-Quinone, thia-Michael addition, Bismuth(III) trifluoromethanesulfonate, vinyl thioethers , ortho-hydroxybenzyl thioethers
