✦ Synopsis
Abstract
β,γ‐unsaturated δ‐hydroxy‐cyclohexene carboxylic acids undergo a smooth decarboxylative elimination when treated with DMF‐dineopentylacetal in an unpolar solvent. The reaction provides a method for the regiospecific preparation of 1,3‐cyclohexadiene derivatives under non‐isomerizing conditions, starting from easily accessible and structurally variable intermediates.
