Copper(I)-Catalyzed Oxidative Coupling between 2-Aminobenzothiazole and Terminal Alkyne: Formation of Benzothiazine
An unprecedented formation of benzothiazine during copper(I)-catalyzed oxidative coupling of 2-aminobenzothiazole and terminal alkyne in air has been observed. This unique transformation possibly occurs through the ring opening of 2-aminobenzothiazole and subsequent oxidative coupling with alkyne followed by intramolecular cyclization. A variety of substituted benzo[b][1,4]thiazine-4-carbonitriles are obtained by this protocol.
But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 154445-78-0, you can contact me at any time and look forward to more communication. Recommanded Product: 2,2,4,6,7-Pentamethyl-2,3-dihydrobenzofuran-5-sulfonyl chloride.
