Abstract: | Compounds and prepared from eugenol () and safrole () respectively were submitted to ozonation in methanol at 0°C. The 3-alkyl muconic acid dimethyl esters were produced from (~ 45%), while starting from the 3-alkyl muconic acid monomethyl esters were obtained regiospecifically (~ 75%). These latter compounds were transformed (~ 85%) into the 4,4-dialkyl butenolides . |
