Diels–Alder Reactions of 1,2-Dihydropyridines: An Efficient Tool for the Synthesis of Isoquinuclidines

The sentence: 'The geometry of the iminium salt and mechanism of the reaction was justified by the formation of a key aqua complex composed of 18 molecules of H₂O and 6 molecules of C₆F₅SO₃H' has been replaced by: 'The geometry of the iminium salt and mechanism of the reaction was justified by the formation of a key aqua complex composed of one molecule of H₂O and three molecules of C₆F₅SO₃H' for the final online version.
