Abstract The intramolecular Diels− Alder reaction of N-allyl-N-(2-furylmethyl) amides to exo- N-acyl-3-aza-10-oxatricyclo [5.2. 1.0 1, 5] dec-8-enes is described. The cycloaddition is controlled not only by the size of the amide appendage, but also by electronegativity of the amide. An example of a new approach towards the synthesis of a highly functionalized pyrrolizidine ring, which links this Diels− Alder cycloaddition to an halogen atom transfer ...
