摘要

Abstract: 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 of benzoic acids, is also ...
