Recyclable hydrotalcite clay catalysed Baylis–Hillman reaction

Abstract

The Baylis–Hillman reaction using ionic liquid/hydrotalcite clay catalytic system has been observed to be more reactive in terms of yield and reaction rate than DABCO/acetonitrile system. During the process, the reactants enjoy ionic liquid/hydrotalcite clay catalytic system and gives corresponding Baylis–Hillman reaction products in good yield. The application of our catalytic system has been diversifying for the synthesis of lactone ceramide analogue from (S)-Garner aldehyde-methyl acrylate using Baylis–Hillman reaction. Recycling of ionic liquid/hydrotalcite clay catalytic system has also been demonstrated in this report. The Baylis–Hillman reaction using ionic liquid/HT-clay catalytic system has been shown to be more reactive in terms of yield and reaction rate than DABCO/acetonitrile system.
