Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 4144-22-3, is researched, SMILESS is O=C(C=C1)N(C(C)(C)C)C1=O, Molecular C8H11NO2Journal, Article, Research Support, Non-U.S. Gov’t, Journal of Organic Chemistry called Ruthenium(II)-Catalyzed C-H Activation of Chromones with Maleimides to Synthesize Succinimide/Maleimide-Containing Chromones, Author is Zhou, Yan; Liang, Hong; Sheng, Yaoguang; Wang, Shaoli; Gao, Yi; Zhan, Lingling; Zheng, Zhilong; Yang, Mengjie; Liang, Guang; Zhou, Jianmin; Deng, Jun; Song, Zengqiang, the main research direction is maleimide regioselective divergent hydroarylation Heck coupling chromone ruthenium catalyst; chromone maleimide succinimide hybrid preparation.Name: 1-(tert-Butyl)-1H-pyrrole-2,5-dione.
An efficient route for the coupling of maleimides with chromones at the C5-position was developed under Ru(II) catalysis. By switching additives, either 1,4-addition products or oxidative Heck-type products were obtained. Benzoic acid led to the formation of 1,4-addition products under solvent-free conditions and silver acetate promoted the generation of oxidative Heck-type products. Various maleimides and chromones were suitable for this transformation, affording the desired products in good to excellent yields in a short reaction time. To understand the mechanism of this reaction, deuteration studies and control experiments were performed.
After consulting a lot of data, we found that this compound(4144-22-3)Name: 1-(tert-Butyl)-1H-pyrrole-2,5-dione can be used in many types of reactions. And in most cases, this compound has more advantages.
