Abstract: A regioselective Michael reaction between aryl methyl ketones and α,β-unsaturated compounds has been carried out using basic polyionic resin as a reusable reagent. Results indicate that the reaction proceeds in consecutive manner as double Michael (27-65%) and triple Michael (40-45%) products with overall yields of 55-80%. Moreover, A-2XMP resin has also been applied on Claisen Schmidt condensations of aromatic aldehydes and ketones (acyclic as well as cyclic) under different reaction conditions yielding dehydrated products in 82-94% yield. The reactions give an opportunity for easy separation, reusability of polyionic resin and easy purification of products in continuous or multiple processing of organic compounds.
