Abstract
The syntheses of p‐substituted 2‐methyl‐4‐phenylbuten(1)‐carboxylic acid derivatives are described, using Blanc's chloromethylation reaction, the Friedel‐Crafts alkylation of unsaturated ketones or the Meerwein arylation; the formed intermediates react in subsequent steps to the title compounds.
