Hetero-Diels-Alder reactions opposing enamines (dihydroquinoline and dihydroisoquinoline derivatives) to substituted nitrosoalkenes are described. The stereoselectivity and regiospecificity of the reactions are discussed. New fused oxazinotetrahydroquinoline and oxazinotetrahydroisoquinoline structures are reported.
