The novel and efficient selenium-catalyzed reductive N-heterocyclization of γ-nitro substituted carbonyl compounds with carbon monoxide has been developed. Various multisubstituted 1H-pyrroles can be easily prepared by this protocol. The one-pot synthesis of ethyl 1H-pyrrole-3-carboxylate derivatives was also successfully attained by the selenium-catalyzed reaction of β-ketoester, vinyl nitro compounds and
已经开发出新颖和有效的硒催化一氧化碳对γ-硝基取代的羰基化合物进行硒催化的还原性N-杂环化。通过该方案可以容易地制备各种多取代的1 H-吡咯。通过硒催化β-酮酸酯,乙烯基硝基化合物和一氧化碳的反应,也成功地完成了1 H-吡咯-3-羧酸乙酯衍生物的一锅法合成。
