An improved synthesis of exo-heterocyclic dienes like TV-substituted 4,5-dimethylene 2-oxazolidinones 1, by a one-step method from diacetyl and isocyanates, was described. This highly convergent synthetic strategy has been successfully used for the prepar
Novel Heterocyclic Outer-Ring Dienes: N-Alkyl- and N-Aryl Substituted 4,5-Dimethylene-2-oxazolidinones

, p. 1951 - 1956 (2007/10/02)
The one-pot synthesis of the hitherto unknown N-substituted 4,5-dimethylene-1,3-oxazolidin-2-ones from diacetyl and the corresponding isocyanate in the presence of triethylamine is described.Diene (4a) undergoes Diels-Alder cycloaddition with N-phenylmale
