1,2,4,5-Tetrazines and 1,2,4-triazines tethered to tryptamine via the ethylamine side chain undergo intramolecular inverse electron demand cycloadditions to produce adducts with the [ABazaCE]-ring skeleton of the Aspidosperma alkaloids.
通过乙胺侧链束缚在色胺上的1,2,4,5-四嗪和1,2,4-三嗪经历分子内逆电子需量环加成反应,生成了具有白色胚芽孢生物碱的[ABazaCE]环骨架的加合物。
