A number of alkynols have been prepared by Sonogashira coupling of propargylalcohol to aromatic halides. Chelation-controlled addition of organometallic nucleophiles to these alkynols was then effected followed by the addition of the sulfur electrophiles, sulfur dioxide or thionylchloride. This methodology was used to prepare a number of oxathiolene oxides, which have been screened as NQO1 (quinone
