The inverse electron demand Diels-Alder reactions of 3-substituted indoles with 1,2,4-triazines and 1,2,4,5-tetrazines proceeded in excellent yields both inter- and intramolecularly. The cycloaddition of tryptophan with a tethered 1,2,4-triazine produced a diastereomerically pure cycloadduct.
3-取代的吲哚与1,2,4-三嗪和1,2,4,5-四嗪的电子反需求Diels-Alder反应在分子间和分子内均以优异的产率进行。色氨酸与束缚的1,2,4-三嗪的环加成反应生成非对映体纯的环加合物。
