Abstract
AbstractThe cyclization reaction and hydrosulfonylation reaction of ynones have been simultaneously realized through a single operation. Under the mediation of cesium carbonate, different S‐(α‐hydroxyaryl) aryl thiosulfonates reacted with various ynones to produce functionalized vinyl sulfones in 37%–83% yields with E‐selectivity. At the same time, a variety of benzoxathiins were formed in 42%–97% yields.
