Intramolecular [2 + 2] Photocycloaddition of 2-Allylindane-1-thiones

Intramolecular [2 + 2] Photocycloaddition of 2-Allylindane-1-thiones

The photochemical reactions of indane‐1‐thiones 4 were examined. Irradiation of indane‐1‐thiones 4c–d bearing δ‐hydrogen atoms in the side chain gave cyclic thiol derivatives 5c–d via δ‐hydrogen atom ion by the excited thiocarbonyl sulfur. Irradiation of 2‐allylindane‐1‐thiones 4e–h afforded the mul...

description The photochemical reactions of indane‐1‐thiones 4 were examined. Irradiation of indane‐1‐thiones 4c–d bearing δ‐hydrogen atoms in the side chain gave cyclic thiol derivatives 5c–d via δ‐hydrogen atom ion by the excited thiocarbonyl sulfur. Irradiation of 2‐allylindane‐1‐thiones 4e–h afforded the multifused thietanes 7e–h by intramolecular [2 + 2] cycloaddition between CS and CC bonds.
