Application of organolithium and related reagents in synthesis. Part XXVIII[1]. Synthesis strategies based on aromatic metallation: a conversion of benzoic acids into arylthiomethyl aromatic carboxylic acids

摘要

A convenient two step protocol preparation of ortho-phenylthiomethyl aromatic carboxylic acids from aromatic carboxylic acids anilides is reported. The phenylthiolation of phthalides with benzenethiol as a key step is described.
