Abstract

Substituted 1 H-2-benzothiopyrans find applications as pharmaceutically active compounds or synthons for more complex sulfur heterocycles. However, restricted variability in their synthesis limits the application for research or industrial purposes. To develop a direct and fast route to substituted and functionalized 1 H-2-benzothiopyrans, we investigated the ring closure of symmetrical bis (arylmethylthio) acetylenes with iodine monochloride or ...
