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 abstraction 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. VCH Verlagsgesellschaft mbH, 1996.

Photoreactivity of α-Tetrasubstituted Arylketones: Production and Asymmetric Tautomerization of Arylenols

In the presence of catalytic amounts of optically active aminoalcohols, the irradiation of α-disubstituted indanones, tetralones and propiophenones bearing at least one hydrogen in the γ-position led to Norrish type II cleavage compounds which were obtained with enantiomeric excesses reaching 89percent.The influence of the reaction conditions (temperature, wavelength of the UV light and nature of the aminoalcohol) has been analyzed.
