Researchers are common within chemical engineering and are often tasked with creating and developing new chemical techniques, frequently combining other advanced and emerging scientific areas. 5872-08-2, Name is (7,7-Dimethyl-2-oxobicyclo[2.2.1]heptan-1-yl)methanesulfonic acid, belongs to thiazines compound, is a common compound. In a pantent, author is Sun, Quan-Shun, once mentioned the new application about 5872-08-2, Recommanded Product: (7,7-Dimethyl-2-oxobicyclo[2.2.1]heptan-1-yl)methanesulfonic acid.
Annulation reaction of methyl 2-(benzo[b][1,4]thiazin-3-ylidene) acetate with beta-nitrostyrenes and 3-nitrochromenes
The acid catalyzed domino reaction of beta-nitrostyrenes with methyl 2-(benzo[b][1,4]thiazin-3-ylidene) acetate, which were previously prepared from the cyclization of 2-aminobenzenethiol and methyl 4-chloroacetoacetate, resulted in 2-arylbenzo[b]pyrrolo[1,2-d][1,4]thiazine-3-carboxylates in high yields. Under same reaction conditions, the similar reaction with 3-nitrochromenes afforded corresponding benzo[b]chromeno[4′,3′:4,5]pyrrolo[1,2-d][1,4]thiazine derivatives in good yields.
