A tandem Aldol condensation/dehydration of aldehydes and ketones could be performed under D-aminoacylase and N-heterocyclic compounds used as co-catalyst in organic media Some control experiments have been designed to demonstrate that either acylase or N-heterocyclic compounds could not catalyze the tandem reaction The acylase showed the highest activity in the presence of imidazole and has been used to catalyze the tandem Aldol condensation/dehydration between different a
