New research progress on 1588-83-6 in 2021. 1588-83-6, Name is 4-Amino-3-nitrobenzoic acid, molecular formula is C7H6N2O4, COA of Formula: https://www.ambeed.com/products/1588-83-6.html, SMILES is C1=C([N+]([O-])=O)C(=CC=C1C(=O)O)N belongs to naphthyridine compound, is a common compound. In a patnet, author is Asahrara, Haruyasu, once mentioned the new application about 1588-83-6.
A practical, convenient, and safe cyano(nitro)methylation method was developed, in which cyano-aci-nitroacetate served as a synthetic equivalent of anionic nitroacetonitrile. A control of the single/double Michael additions was achieved, which enabled the synthesis of unsymmetrical double Michael adducts. Moreover, the Michael adducts can be used as precursors of pyridine and naphthyridine frameworks. (C) 2014 Elsevier Ltd. All rights reserved.
