Expeditious ‘On-Water’ Cycloaddition between N-Substituted Maleimides and Furans

Abstract

Cycloaddition reactions between <i>N</i>-alkyl and <i>N</i>-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 quantitative yields.
