Abstract
The one-pot synthesis of the hitherto unknown N-substituted 4,5-dimeth ylene-1,3-oxazolidin-2-ones from diacetyl and the corresponding isocya nate in the presence of triethylamine is described. Diene (4a) undergo es Diels-Alder cycloaddition with N-phenylmaleimide (10), and, in the absence of a dienophile, gives a mixture of dimers (12) and (13), and the ring closure cyclobutene (14).
