A One-pot Facile Synthesis of 2,3-Dihydroxyquinoxaline and 2,3-Dichloroquinoxaline Derivatives Using Silica Gel as an Efficient Catalyst

An efficient one-pot reaction has been developed for the synthesis of 2,3-dichloroquinoxaline derivatives 3a?n. The reaction was performed in two steps via a silica gel catalyzed tandem process from o-phenylenediamine and oxalic acid, followed by addition of phosphorus oxychloride (POCl3). A variety of 2,3-dichloroquinoxalines have been obtained in good to excellent overall yields. Eight known compounds 3a?3h were characterized by IR, 1H-NMR, and mass spectroscopies. Compounds 3i?3n without spectroscopic data were characterized by IR, 1H-NMR, 13C-NMR, and mass spectroscopies.

One-pot synthesis of quinoxalines from reductive coupling of 2-nitroanilines and 1,2-diketones using indium

The one-pot reduction-cyclization of 2-nitroanilines and 1,2-diketones to give quinoxalines was investigated. Using indium and an appropriate acid such as acetic acid or indium(III) chloride, various quinoxaline derivatives including 2,3-dialkylquinoxalines, 2,3-diphenylquinoxalines, 2,3-di-2-thiophenylquinoxalines, 2,3-di(pyridin-2-yl)quinoxalines, and dibenzo[a,c]phenazines were synthesized in moderate to excellent yield.

2-mercapto-4-pyridyl thiazole synthesis method (by machine translation)

The invention discloses a synthesis method of 2-sulfydryl-4-pyridyl thiazole. According to the technical scheme, 4-acetylpyridine serving as a raw material has a bromination reaction, and then ammonium dithiocarbamate is directly added to for reaction to obtain the 2-sulfydryl-4-pyridyl thiazole. The method is simple, efficient and mild in conditions, the intermediate is a bromide, the target product can be obtained by a one-pot process without purification, and the harm of the intermediate to a human body can be greatly reduced; and moreover, the obtained product is high in purity and yield and very suitable for industrial production.

Recent developments in the use and abuse of growth promoters

During the last few years, control within the European Union (EU) for illegal growth promoters in cattle and pigs revealed only a limited number of positives. Analysis of illegal preparations, however, showed that steroids, often (esters of) natural hormones, and beta-agonists are still used. Corticosteroids, controlled to a much lesser extent, seem to have become the most important group, while even thyreostats remain. Alarming information was obtained from specific investigations in which a large variety of products were found, some of which had never been reported to be misused in the field of growth promotion. For beta-agonists and quinoxaline compounds, analogues of known compounds are synthesised. Other compounds are readily available as they are registered as growth promoters in some countries outside Europe or are allowed for specific veterinary purposes. Some classes of veterinary drugs are misused for their secondary pharmacological effects, e.g. benzodiazepines as feed intake enhancers and non-steroidal anti-inflammatory drugs (NSAIDs) as pale meat-making agents. Several non-traditional substances are suspected to be used in the field of breeding animals. This is the case for growth hormones (GHs) and all substances acting over this anabolic compound, as for instance, orally GH secretagogue. Moreover, ecdysteroids, which according to old Russian studies, have anabolic activity, are actually very easy to purchase on the Internet. Recent findings in different classes of growth promoters are discussed in detail.

Facile synthesis and anti-proliferative activity evaluation of quinoxaline derivatives

A series of ?drug-like? compounds based on quinoxaline scaffold with arylsulfonyl hydrazinyl, arylformyl hydrazinyl or arylsulfonyl groups at C-2 and aryloxy groups at C-3, were synthesized in 4 or 5 steps involving cyclization, chlorination and coupling reactions. Cellular anti-proliferative activities of these quinoxaline derivatives in vitro were determined, which revealed that the inhibitory potency and selectivity of 6f was comparable to that of the positive control.
