Abstract
The intramolecular Diels-Alder reactions between acyclic dienes and α, β-unsaturated amides utilizing the internal coordination of the metal salts have been studied in detail. When the magnesium salts of N-(trans, trans-2, 4-alkadienyl)-N-(2-hydroxyphenyl) acrylamide derivatives are employed, the intramolecular Diels-Alder reactions are remarkably accelerated and the corresponding cycloadducts are obtained in high yields ...
