aspects of the intramolecular Diels-Alder reaction on perhydro-1,3-benzoxazines derivedfrom (-)-8-aminomenthol bearing α,β-unsaturated amides and the dienic component attached at C-2 are described. The thermal cyclization of 2-(2'-furyl) derivatives 2, 6, and 7 exclusively afforded mixtures of exo adducts. The product selectivity was highly dependent on the solvent of the reaction. In CH2Cl2, the
