Mg-Al-O-t-Bu hydrotalcite:: a new and efficient heterogeneous catalyst for transesterification

Normal and beta-ketoesters have been successfully transesterified with primary, secondary, unsaturated, allylic, cyclic, hindered alcohols and amines by Mg-Al-O-t-Bu hydrotalcite catalyst for the first time affording excellent yields of products at a faster rate under heterogeneous catalysis.
