Thioallenoates in catalytic enantioselective [2+2]-cycloadditions with unactivated alkenes

Article abstract of DOI:10.1016/j.tet.2019.04.028

The application of thioallenoates to catalytic enantioselective [2+2]-cycloadditions with unactivated alkenes is reported. In many cases, the thioallenoates examined exhibit superior reactivity and selectivity compared to the allenic esters generally used in these cycloadditions.
