Cycloaddition reactions between N-alkyl and N-aryl-substituted maleimides and furan derivatives have been carried out using the 'on-water' methodology. Transformations are faster and products can easily be isolated by simple workup protocols, often in qua

The reaction of furan with α,β-unsaturated carbonyl dienophiles catalyzed by K10 montmorillonite in the absence of organic solvents produces the corresponding Diels-Alder adducts and, in the case of methyl vinyl ketone, Michael-type products, under much milder conditions than the conventional protocols. The results are consistent with acid catalysis on the clay surface. Acrylates gave lower yields and/or decomposition products. The reaction can be extended to alkynic substrates such as DMAD to afford cycloadducts in good yields.
