A model catalytic oxygenation for the reaction of quercetinase
Abstract
Bis(salicylidene)ethylenediaminatocobalt(II) catalyses the oxygenation of 3-hydroxyflavones in dimethylformamide giving rise to oxidative cleavage of the heterocyclic ring of the flavones to give the corresponding depsides in excellent yield; this provides a nonenzymic model for the reaction of quercetinase.
