Abstract
[GRAPHICS] The type 2 intramolecular Diels-Alder cycloaddition utilizing N-acylnitroso dienophiles provides an efficient entry into bridged oxazinolactams. In co ntrast to the bimolecular counterpart, the reaction is completely regiosele ctive, Structural characterization of the cycloadducts allows for evaluatio n of the olefin distortion and the degree of pyramidalization of the bridge head oxazinolactam.
