Formation of dehydrodiisoeugenol and dehydrodieugenol from the reaction of isoeugenol and eugenol with DPPH radical and their role in the radical scavenging activity

The aim of this work was to investigate the products of the reactions between isoeugenol and eugenol with the stable 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical and their role in the radical scavenging mechanism. The reaction of isoeugenol and eugenol with the DPPH radical produced, as evidenced by GC-MS and HPLC-MS, a complex mixture of dimeric species in which dehydrodiisoeugenol and its adducts with methanol (reaction solvent) and dehydrodieugenol were the main reaction products, respectively. The antioxidant activity of dehydrodiisoeugenol, determined by the DPPH method, resulted lower than that of isoeugenol considering both the parameters Effective Concentration (EC50) and Antiradical Efficiency (AE). In particular, due to its very slow kinetic behaviour (TEC50 = 201 min), the possible contribution of dehydrodiisoeugenol to the DPPH radical scavenging activity of isoeugenol (TEC50 = 3.1 min) was practically negligible. On the contrary, dehydrodieugenol had an antioxidant activity higher than that of eugenol and its lower TEC50 (85 min with respect to 126 min) made it possible to contribute to the DPPH radical scavenging activity of eugenol.

An efficient and flexible synthesis of model lignin oligomers

The use of model compounds in the development of selective lignin depolymerisation processes has been limited by the lack of complexity of these models compared with lignin itself. In this paper we report a convergent and efficient synthetic method for th

Stereoselective synthesis of 8,9-licarinediols

The total synthesis of 8,9-licarinediols was selectively carried out from licarin A, previously obtained by oxidative coupling of (E)-isoeugenol. The corresponding enantiomerically pure (+)- and (-)-licarin A ester derivatives were subjected to Sharpless oxidation to yield the asymmetric C-8, C-9 dihydroxylation products, whose absolute configurations were established by means of the CD and NMR spectroscopic analyses of their Mosher ester derivatives.
