Abstract
[reaction--see text] The type 2 intramolecular Diels-Alder cycloaddition utilizing N-acylnitroso dienophiles provides an efficient entry into bridged oxazinolactams. In contrast to the bimolecular counterpart, the reaction is completely regioselective. Structural characterization of the cycloadducts allows for evaluation of the olefin distortion and the degree of pyramidalization of the bridgehead oxazinolactam.Entities:
