Abstract: While abundant information on the reactivity of several classes of nitrones exists [1], hetaryl nitrones, i.e. nitrones bearing an heterocyclic ring at the carbon atom, have been the subject of very few investigations [2]. Recent publications from our laboratory have been concerned with the use of thiazolyl nitrones 1 as a suitable substrate for both nucleophilic additions [3] and 1,3-dipolar cycloadditions [4]. Our continued interest in the reactivity of hetaryl nitrones has led to investigate the reaction of the furfuryl nitrones 2 with several alkenes. In this communication we report our preliminary results on this topic.
