The synthesis of twelve tetrahydro‐β‐carboline derivatives 3a, 3b, 3c, 3d, 3e, 3f, 3g, 3h, 3i, 3j, 3k, 3l prepared via the Pictet–Spengler reaction is described. The reaction of tryptamine and a variety of arylaldehydes were carried out under ultrasonic irradiation and trifluoracetic acid catalysis at room temperature. These tetrahydro‐β‐carbolines have been synthesized in higher yields and shorter
十二种四氢-β-咔啉衍生物3a,3b,3c,3d,3e,3f,3g,3h,3i,3j,3k,3l的合成描述了通过Pictet-Spengler反应制备的方法。在室温下,在超声辐射和三氟乙酸催化下,进行了色胺与多种芳基醛的反应。与传统方法相比,这些四氢-β-咔啉的合成产率更高,反应时间更短。此外,即使使用带有给电子或吸电子取代基的芳醛也能成功进行反应,而这些取代基在常规方法下不会发生反应。
