di-7-azaindolylmethanes (DAIMs) is reported. Under MAOS conditions, reaction of 7-azaindole with aldehydes resulted predominantly in DAIMs, as opposed to the expected 7-azaindole addition products that form at ambient temperature. Based upon studies of different indoles and azaindoles with various aromatic and aliphatic aldehydes, we herein propose a mechanism where rapid and efficient microwave heating
报道了一种利用微波辅助有机合成 (MAOS) 产生二-7-氮杂吲哚基甲烷 (DAIM) 的新型高效合成方法。在 MAOS 条件下,7-氮杂吲哚与醛的反应主要产生 DAIM,而不是在环境温度下形成的预期 7-氮杂吲哚加成产物。基于对具有各种芳香族和脂肪族醛的不同吲哚和氮杂吲哚的研究,我们在此提出了一种机制,其中快速有效的微波加热促进了 7-氮杂吲哚对相应的亚烷基-氮杂吲哚中间体的亲核性,以形成 DAIM。该序列提供了一种有效合成可能是有用药物的新型 DAIM 的通用方法。
