✦ Synopsis

Intramolecular hetero-Diels-Alder reaction of a tethered alkoxycarbonylnitroso-containing triene proceeds with complete stereoselectivity. Cleavage of the tethering group and further synthetic elaboration of the cycloadduct is described.

## Abstract The Diels‐Alder reaction of __cis__‐5,6‐diacetoxy‐1,3‐cyclohexadiene (1), which has a __meso__ configuration, with the chiral nitroso dienophile 2 occurs with induction of four asymmetric centers in very high optical yield (ee = 94%) and leads to the dihydro oxazine 3 (89%).
