We have reported a one-pot two-step methodology for the synthesis of highly condensed heterocycles, pyrrolo[1,2-a][1,4]benzodiazepines, by a modified Pictet–Spengler reaction under mild conditions in a short time. Our approach has a few advantages over the conventional two components synthesis as it is step and atom economic, environmentally benign and a convergent synthetic method. We have discussed
我们已经报道了在改良的Pictet-Spengler反应中在短时间内在改良的Pictet-Spengler反应中合成高浓缩杂环,吡咯并[1,2- a ] [1,4]苯并二氮杂物的一锅两步方法。我们的方法相对于常规的两组分合成方法具有一些优势,因为它是一步法和原子经济,对环境有益的方法,并且是一种收敛的合成方法。我们在这里讨论了这种新颖方法的广泛的基质范围。
