  Photochemistry of Substituted 4,4-Dimethoxy-2,5-Cyclohexadienones

  摘要：

  Abstract4,4‐Dimethoxy‐2,5‐cyclohexadienones 9–14 were prepared from the corresponding hydroquinone monomethyl ethers by oxidation with thallium trinitrate in methanol. Irradiation of solutions of 9–13 in methanol with a broad band of UV light centered at 350 nm in a Rayonet reactor afforded 2‐cyclopentenone derivatives 15–19 in moderate to excellent yields, whereas irradiation of 14 in methanol gave phenol 8 along with other unidentified products. Irradiation of 11–14 in benzene yielded substituted phenols. The plausible reaction pathways for the product formation are discussed.

  Alkylated 4,4-dimethoxy-2,5-cyclohexadienones were irradiated in methanol to give 2-cyclopentenones derivatives in fair yields. Methyl ester of (±)-desepoxy-2,5-didehydromethylenomycin A was prepared from 2,3-dimethylhydroquinone monomethyl ether in four steps and 36% overall yield using this photochemical reaction as a key step.
