New discoveries in chemical research and development in 2021. 1588-83-6, Name is 4-Amino-3-nitrobenzoic acid, molecular formula is C7H6N2O4, Computed Properties of https://www.ambeed.com/products/1588-83-6.html, belongs to naphthyridine compound, is a common compound. In a patnet, author is Feng Lian-shun, once mentioned the new application about 1588-83-6.
A new route for the synthesis of DW286, 7-[3-(aminomethyl)-4-(methoxyimino)-3-methyltetrahydro-1H-1-pyrrolyL]-1-cyclopropyl-6-fluoro-4-oxo-1,4-dihydro[1,8]naphthyridine-3-carboxylic acid hydrochloric acid salt, is described. In the presence of benzadehyde, DW286 was prepared by the direct condensation of 7-chloro-1-cyclopropyl-6-fluoro-4-oxo-1,4-dihydro[1,8]naphthyridine-3-carboxylic acid with new pyrrolidine derivative 7 which could be obtained by routine reactions.
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 1588-83-6. Computed Properties of https://www.ambeed.com/products/1588-83-6.html.
