4-Bromoindoline-2,3-dione (cas: 20780-72-7) belongs to indole derivatives. The indole subunit is an almost ubiquitous component of biologically active natural products, and its study has been the focus of research for decades. Due to this activity, the indole ring system has become an important component or intermediate in the synthesis of heterocycles.Application of 20780-72-7

Iodine-Catalyzed Aerobic Oxidation of Spirovinylcyclopropyl Oxindoles to Form Spiro-1,2-dioxolanes Diastereoselectively was written by Xiong, Cheng;Cheng, Kunpeng;Wang, Jiahua;Yang, Fulai;Lu, Jinrong;Zhou, Qingfa. And the article was included in Journal of Organic Chemistry in 2020.Application of 20780-72-7 This article mentions the following:

A novel method of iodine-catalyzed aerobic oxidation with spirovinylcyclopropyl oxindoles under mild conditions has been described. A series of spiro-1,2-dioxolanes were prepared in good to excellent yields and considerable diastereoselectivities. The new approach is operationally simple, scalable, and tolerant of various functional groups. In the experiment, the researchers used many compounds, for example, 4-Bromoindoline-2,3-dione (cas: 20780-72-7Application of 20780-72-7).
