REACTION OF AZOMETHINE N-OXIDES. PART 4. A NEW MODE OF REACTION OF AZOMETHINE N-OXIDES WITH DIBENZOYLACETYLENE

El-Din, Ahmed Moukhtar Nour,Mourad, Aboul-Fetouh El-Said,Mekamer, Ramadan

, p. 1155 - 1160 (2007/10/02)

A new mode of 1,3-dipolar cycloaddition reaction with dibenzoylacetylene as dipolarophile was observed.The addition of this dipolarophile to diffrent substituted open chain N-arylnitrones afforded 3-anilino-1,4-diphenylbutane-1,2,4-trione.Its formation by 1,3-dipolar cycloaddition reaction followed by intermolecular rearrangement and ylide decomposition is discussed.On the other hand, the conformationally rigid cyclic nitrones form either 4-oxazoline or enamine compounds.
