Abstract

Irradiation (Ξ» =313 nm) of the 4‐pyrrolin‐3‐ones 1a–1c in acetone‐, 3‐pentanone‐and cyclopentanone solution affords the title compounds 2, formally via H‐abstrac‐tion by the excited ketone and recombination of the radical pair formed.

Photolysis (A = 254 nm) of 4-(tert-butyl)-4,6,7,8-tetrahydro-7,7-dimethyl-2H-l-benzopyran-2,5(3H)-dione (3a) in t-BuOH affords 2-(2,2-dimethylpropylidene)-5,5-dimethyl-l,3-cyclohexanedione (la) in 80% yield via homolysis of the lactone 0-CO bond and subsequent ketene elimination.
