The synthesis of the 3-arylphthalides 3 via metallation (BuLi) of the benzanilides 1 and subsequent reaction of the generated bis-lithiated anilides 2 with aromatic aldehydes is described. Conversion of 3 into the corresponding 2-(1-aryl-2-methoxycarbonylethyl)benzoic acids 4 by treatment with 1-methoxy-1-trimethylosiloxyethene in the presence of titanium tetrachloride, as a way of regiospecific transformation

carbon atoms alkyl chain) aromatic carboxylic acids from benzoic acids anilides is described. Ortho -lithiation of benzanilides and subsequent reaction of the generated bis( N - and C - ortho -)-lithiated anilides with aromatic aldehydes provided 3-arylphthalides. In the next step, these phthalides were converted into 5-(2-carboxyphenyl)-5-phenylpent-2-enoic acids by treatment with 1-methoxy-1-trimethylsilyloxybuta-1
