Method for synthesizing benzoxazole compound by using nitration by-products of aromatic hydrocarbon and application of benzoxazole compound

The invention discloses a method for synthesizing a benzoxazole compound by using nitration by-products of aromatic hydrocarbon and application of the benzoxazole compound. The method comprises the main process: performing step-by-step crystallization on nitration products of a 2,4-dinitrochlorobenzene production enterprise so as to obtain 2,4-dinitrochlorobenzene, 2,6-dinitrochlorobenzene (I) anda small amount of residues, adopting the obtained 2,6-dinitrochlorobenzene (I) as the main starting material, and performing hydrolysis, selective catalytic hydrogenation reduction, cyclization, halogenation, carbon-carbon coupling and other processes so as to synthesize the benzoxazole compound, wherein the obtained compound can be used as a main raw material to synthesize a series of chemical intermediates with important application, and the chemical intermediates include o-aminophenol, 2-amino-4-nitrophenol, 2-amino-5-nitrophenol and hydrochloride of o-aminophenol, 2-amino-4-nitrophenol, 2-amino-5-nitrophenol. Through the method, the industrial by-products are converted into high value-added aromatic aminophenol products, industrial hazardous waste of the 2,4-dinitrochlorobenzene production enterprise is reduced, the scope of products of the enterprise is widened, and the economic benefits of enterprise are increased.

2-Aminobenzoxazole ligands of the hepatitis C virus internal ribosome entry site

2-Aminobenzoxazoles have been synthesized as ligands for the hepatitis C virus (HCV) internal ribosome entry site (IRES) RNA. The compounds were designed to explore the less basic benzoxazole system as a replacement for the core scaffold in previously discovered benzimidazole viral translation inhibitors. Structure-activity relationships in the target binding of substituted benzoxazole ligands were investigated.

Synthesis and biological evaluation of piperazinyl heterocyclic antagonists of the gonadotropin releasing hormone (GnRH) receptor

Antagonism of the gonadotropin releasing hormone (GnRH) receptor has resulted in positive clinical results in reproductive tissue disorders such as endometriosis and prostate cancer. Following the recent discovery of orally active GnRH antagonists based on a 4-piperazinylbenzimidazole template, we sought to investigate the properties of heterocyclic isosteres of the benzimidazole template. We report here the synthesis and biological activity of eight novel scaffolds, including imidazopyridines, benzothiazoles and benzoxazoles. The 2-(4-tert-butylphenyl)-8-(piperazin-1-yl)imidazo[1,2-a]pyridine ring system was shown to have nanomolar binding potency at the human and rat GnRH receptors as well as functional antagonism in vitro. Additional structure-activity relationships within this series are reported along with a pharmacokinetic comparison to the benzimidazole-based lead molecule.

Nitration of o-Aminophenol, o-Anisidine, and o-Benzenediazonium Oxide in Sulfuric Acid

Entering into a reaction in the protonated form, o-aminophenol is nitrated in 80% sulfuric acid at the para and ortho positions to the hydroxy group to afford a mixture of 4-nitro- and 6-nitro-2-aminophenol and is nitrated and sulfonated in concentrated sulfuric acid, whereas o-anisidine is nitrated at the para positions in both cases, converting into 4-nitro-2-aminoanisole. After diazotization of o-aminophenol and subsequent nitration of o-benzenediazonium oxide, a mixture of the same derivatives as in diazotization of the nitration products of o-aminophenol is formed, but the 6-nitro isomer prevails.
