21. Using a retro Diels-Alder reaction , structure 5 was formed in near quantitative yield. 22. The insecticide aldrin, created through a Diels Alder reaction , is also named after the scientist. 23. For example, an analog for the Diels-Alder reaction is the quadricyclane-DMAD reaction: 24. This prediction agrees with experiment as the Diels-Alder reaction is a rather facile pericyclic reaction. 25. This could be used as a starting point for all sorts of useful Diels-Alder reactions . 26. Hydrogen-bonded glycouril dimer catalyst developed by Julius Rebek Jr . for Diels-Alder reactions . 27. Synthetic applications of the Diels-Alder reaction have been discussed extensively in a series of review articles. 28. Other reactions with apolar reactants such as Ene reactions and Diels-Alder reactions also exhibit rate accelerations. 29. In the model studies to synthesize chlorothricolide, an intramolecular Diels Alder reaction gave a mixture of diastereomers. 30. Under acidic conditions a Diels-Alder reaction of ?-( dehydroprenyl ) indole can produce yuehchukene.
