Efficientregioselectiveconjugateadditions of thiophenols and ben- zotriazole to 4-aryl-4-oxobut-2-enoates were achieved under mild conditions. Thus, a variety of 2-(arylthio)-4-oxo-4-arylbutanoates and 2-benzotriazolyl-4-oxo- -4-arylbutanoates were conveniently synthesized in good to excellent yields.
