- 中文摘要: 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% and 53% overall yields, respectively. Photochemical rearrangements of masked p-benzoquinones in methanol are the key steps.
