—— | 2-[1-(4-methoxyphenyl)-3-oxobutyl]-benzoic acid | 569343-15-3 | C18H18O4 | 298.339 |
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.
