The syntheses of methyl ester of (±)-desepoxy-4,5-didehydromethylenomycin A (4) and 2,3-dimethyl-5-methoxycarbonyl-2-cyclopentenone (5) were accomplished from a common starting material, 2,3-dimethyl-4-methoxyphenol (8), in only four and two steps in 35%

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