  • Laccase-catalyzed oxidative phenolic coupling of vanillidene derivatives
    作者:Mihaela-Anca Constantin、Jürgen Conrad、Uwe Beifuss
    DOI:10.1039/c2gc35848d
    日期:——
    The laccase-catalyzed oxidative phenolic coupling of vanillidene derivatives using aerial oxygen as the oxidant has been developed. Depending on the substitution pattern of the vanillidene double bond of the substrate, either dilactones, dihydrobenzo[b]furans or biphenyls are formed.
