approach has been employed to synthesize a variety of indole and carbazole derivatives from nitroarenes, surprisingly, very little is reported for making pyrroles using the same approach from non-arene nitrodienes. Herein, we report a general method to synthesize substituted pyrroles, in one step with modest yields, from nitrodienes using triphenylphosphine in the presence of an Mo catalyst, bis(acetyl
尽管已经采用了Cadogan-Sundberg方法从硝基芳烃合成各种吲哚和咔唑衍生物,但令人惊讶的是,很少有人报道使用相同的方法由非芳烃硝基二烯制备吡咯。在这里,我们报告了一种通用的方法,该方法可以在Mo催化剂双(乙酰乙酰基)二氧钼钼(VI)存在下,使用三苯基膦从硝基二烯以适度的产率合成取代的吡咯。为了阐明该反应的机理,我们使用uB3LYP / 6-31 + G(d)基集进行了DFT计算,并观察到该反应有利于通过腈中间体的路径。
