The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: 2-Bromo-1-(1-methyl-1H-pyrrol-2-yl)ethanone, is researched, Molecular C7H8BrNO, CAS is 65438-97-3, about 4-Acetylamino-3-(imidazol-1-yl)-benzoic acids as novel inhibitors of influenza sialidase, the main research direction is acetylaminoimidazolylbenzoic acid preparation influenza sialidase inhibitor; imidazolylbenzoic acid preparation influenza sialidase inhibitor; benzoic acid imidazolyl preparation influenza sialidase inhibitor; virucide anti viral agent acetylaminoimidazolylbenzoic acid.Category: naphthyridine.
Two methods for the synthesis of 4-acetylaminobenzoic acids substituted at the 3-position with imidazoles are described. Thus, 4-acetylamino-3-aminobenzoic acid tert-Bu ester was N-alkylated with RCH2COBr (R = Ph, Et, benzofuran-3-yl, etc.) followed by cyclization with cyanamide and hydrolysis to give imidazolylbenzoic acids I (R1 = Ph, furyl, Et, etc.; R2 = NH2). Imidazolylbenzoic acids I (R1 = H; R2 = NH2, H, Et) were prepared by addition of the appropriate imidazole to 3-fluoro-4-nitrobenzoic acid tert-Bu ester followed by reduction of the nitro group, acetylation, and hydrolysis. Many of the compounds are inhibitors of influenza virus sialidases with levels of activity similar to the recently described 4-acetylamino-3-guanidino-benzoic acid (BANA 113).
