Given the importance of this class of compounds in this study we investigate the catalytic effect of L-proline in synthesis of this class of heterocyclic compounds.
Strong activity of compound (2a) and weak to moderate activity of compounds (1a), (2a) and (2b) can be explained on the basis of presence of electron-withdrawing and electron-donating groups in the aromatic rings of the heterocyclic compounds that might play an important role in radical scavenging activity.
Lipid-derived compounds in meat volatiles have greater odour threshold values (Table 3) as opposed to sulfur- and nitrogen-containing heterocyclic compounds which make them less aroma significant.
