A novel and efficient metal-free synthesis of phenolic compounds was developed via coupling cyclization of DMF as a carbon source with active methylene compounds such as 1,3-dicarbonyl compounds with the assistance of 1,1-dichloro-2-nitroethene. The method we used was different from other traditional phenol functionalization methods. In the reaction, the 1,1-dichloro-2-nitroethene as a promoter which
通过将作为碳源的DMF与活性亚甲基化合物(例如1,3-二羰基化合物)在1,1-二氯-2-硝基乙烯的辅助下偶联环化,开发了一种新颖,有效的无金属酚类化合物合成方法。我们使用的方法不同于其他传统的苯酚官能化方法。在反应中,1,1-二氯-2-硝基乙烯作为促进剂,这与我们先前对1,1-二氯-2-硝基乙烯的研究不同。该方法允许在温和的反应条件下以中等收率方便地构建酚类化合物。
