—— | 4-methoxy-2-[1-(2-methoxyphenyl)-3-oxo-4-propoxycarbonylbutyl]-benzoic acid | —— | C23H26O7 | 414.455 |
The ortho-lithiation of a benzoic acid anilide followed by condensation with an aryl aldehyde gave a 3-arylphthalide. Reductive alkylation with 1-methoxy-1-trimethylsilyloxyethene gave a substituted aromatic carboxylic acid which was cyclised to an anthrone bearing a methoxycarbonyl methylene unit at C-10.
