✦ Synopsis

Lewis acid catalyzed condensation of unsaturated orthofonnates with dienol ethers gives enone-acetals suitable for intramolecular photocycloadditions, yielding heterocyclic precursors to sesquiterpene lactones.

## Abstract 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

## Abstract The effect of substituents (X  H, Me, or F at C(6), R  H or Me at C(2′) of the allyl side chain) on the photoisomerization (λ = 350 nm) of 6‐allylcyclohex‐2‐enones 1 in MeCN is studied. Substituents X control the overall efficiency of intramolecular [2 + 2] photocycloadduct formation
