Abstract
Starting from the photocycloaddition of methyl 2,4-dioxopentanoate with 4-isopropenyltoluene, isolaurene was synthesized, and its further conversion to 5-cuparenone constituted the formal synthesis of cuparene. For the first time, the proto-(2+2)π cycloadduct, a β-keto cyclobutanol derivative, has been isolated from the product mixture.
