From the reaction between cysteine and 2,5-dimethyl-4-hydroxy-3(2H)-furanone (DMHF) at 160 °C for 0.5 h at pH 2.2 in a closed system, 24 volatile components are identified including two novel compounds, 3-methyl-2-(2-oxopropyl)thiophene and 2-methyl-3-propionylthiophene. These compounds along with 2,4-hexanedione appear to be the major products from the reaction of cysteine and DMHF, based on a comparison of the results obtained from this system with those previously reported from the individual reactants under the similar conditions. The formation mechanism of these thiophenes is proposed.
