Zusammenfassung:
The synthesis of two C-acylimines and their reactivity towards electron rich dienophiles inDiels-Alder reactions is described. A [4+2] cycloadduct is obtained only in one case: from the reaction of a C-acylimine substituted by two methoxycarbonyl groups with tetraethoxyethylene. No [2+2] cycloadducts are observed.
