We have developed a highly atom efficient synthesis of tetrasubstituted 3(2H)-furanones from easily accessible starting materials such as C,N-diarylaldonitrones and dibenzoylacetylene. Control experiments revealed that reaction of aldonitrones having

Depending on the nature of N- and C-substituents, nitrones exhibit diverse reactivity towards electron deficient acetylenes. Observed reactions include formal 1,3-dipolar cycloaddition and nucleophilic addition reactions. Possible involvement of zwit
