title: Oxathiolene oxide synthesis via chelation-controlled addition of organometallic reagents to alkynols followed by addition of sulfur electrophiles and evaluation of oxathiolene oxides as anticarcinogenic enzyme inducers.
abstract: A number of alkynols have been prepared by Sonogashira coupling of propargyl alcohol 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 thionyl chloride. This methodology was used to prepare a number of oxathiolene oxides, which have been screened as NQO1 (quinone oxidoreductase) inducers.
