| Abstract: | Tungstophosphoric acid catalyzed rapid and good yielding reactions of α,β-unsaturated aldehydes with arenethiols to give the corresponding 4-thioaryl-1,2,3,4-tetrahydro-1-benzothiopyrans (thiochromans) under solvent-free and room temperature conditions. |
| Keywords: | Thiochroman α,β-Unsaturated aldehyde Arenethiol Tungstophosphoric acid Intermolecular cycloaddition |
