New discoveries in chemical research and development in 2021. 40138-16-7, Name is (2-Formylphenyl)boronic acid, molecular formula is C7H7BO3, SDS of cas: 40138-16-7, belongs to naphthyridine compound, is a common compound. In a patnet, author is Blanco, Maria Mercedes, once mentioned the new application about 40138-16-7.
The study of the reactivity of a series of isatin-1-acetamides with hot alkoxides is described. These reactions lead to 1,4dihydro-3-hydroxy-4-oxo-2-quinolinecarboxamides as main products, and 3-hydroxy-2-oxindoles as well as other minor products. Experimental results indicate that the starting compounds undergo transformation through two principal routes: ring expansion of isatin leading to quinoline carboxamides, probably as the result of a ring-opening and ring-closure rearrangement, and reduction of the keto carbonyl group due to the reductive ability of alkoxides.
Future efforts will undeniably focus on the diversification of the new catalytic transformations. In my other articles, you can also check out more blogs about 40138-16-7. SDS of cas: 40138-16-7.
