scope of 1,3,5-triazine inverse electron-demand Diels-Alder (IDA) reactions was expanded to include 2-aminoindoles as productive dienophiles leading to various 3-aza-α-carbolines in excellent yields. Furthermore, the two ester groups of the IDA product were differentiated via reduction of the C4-ester to its corresponding alcohol. This new IDA reaction could be potentially applied to the synthesis of
1,3,5-三嗪逆电子需求 Diels-Alder (IDA) 反应的范围扩大到包括 2-氨基吲哚作为生产亲二烯体,从而以优异的产率获得各种 3-氮杂-α-咔啉。此外,IDA 产品的两个酯基团是通过将 C4-酯还原为其相应的醇来区分的。这种新的 IDA 反应可用于合成各种可能具有神经保护活性的 3-氮杂-mescengrincin 类似物。
