o-Quinone derivatives are not only a variety of active and important intermediate, but also widely used in the synthesis of natural products and medicinal chemistry. In the present study, the Sc(OTf)3 catalyzed oxo-Michael addition to o-quinone methides by alcohols was developed. The products were obtained in moderate to good yields (76%~97%) under mild conditions. Furthermore, the reaction could be scaled up to multigram scale.

Key words: o-quinone, scandium(III) triflate, oxo-Michael addition, green chemistry
