—— | 2-[2-(2,2-dimethyl-6-oxo-6H-[1,3]dioxin-4-yl)-1-(4-methoxyphenyl)-ethyl]-3-methoxy-benzoic acid | 918536-55-7 | C23H24O7 | 412.439 |
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.
