Article abstract of DOI:10.1246/cl.1990.1185

Reaction of the acetylenic alcohols with arenethiols in the presence of p-toluenesulfonic acid (p-TsOH) gave 3,4-dihydro-2H-1-benzothiopyrans (thiochromans) in good to excellent yields, the reaction of which may involve intermolecular cycloaddition via ca
