Markovnikov addition of imidazole derivatives with vinyl esters catalyzed by lipase TL IM from Thermomyces lanuginosus/K2CO3 in a continuous-flow microreactor

In this work, a simple and efficient method for Markovnikov addition of imidazole derivatives to vinyl esters catalyzed by Lipozyme TL IM/K2CO3 in a continuous-flow microreactor was described. The effects of the mixed catalysts, molar ratio and the structure of reactants on the reaction performance were experimentally studied. The attractive features of this process are shorter reaction times (30 min) and excellent yields compared to that in shaker reactors.
