Wu, Yue;Guo, Peng;Chen, Long;Duan, Weijie;Yang, Zengzhuan;Wang, Tao;Chen, Ting;Xiong, Fei published 《Iron-catalyzed tandem oxidative coupling and acetal hydrolysis reaction to prepare formylated benzothiazoles and isoquinolines》 in 2021. The article was appeared in 《Chemical Communications (Cambridge, United Kingdom)》. They have made some progress in their research.Recommanded Product: 6-Nitrobenzo[d]thiazol-2-amine The article mentions the following:
The direct formylation of benzothiazoles and isoquinolines was reported. The reaction features a novel iron-catalyzed Minisci-type oxidative coupling process using com. available 1,3-dioxolane as a formylated reagent followed by acetal hydrolysis without a separation process. The reaction was performed under exceedingly mild reaction conditions and exhibited broad functional group tolerance. The experimental procedure involved many compounds, such as 6-Nitrobenzo[d]thiazol-2-amine (cas: 6285-57-0) .
6-Nitrobenzo[d]thiazol-2-amine(cas:6285-57-0Recommanded Product: 6-Nitrobenzo[d]thiazol-2-amine) has been shown to lower blood pressure in mice by inhibiting angiotensin converting enzyme and potassium channels. This drug also has a protective effect on the heart and brain from ischemia reperfusion injury.
