Determination of Neutral Manufacturing Impurities in Heroin by Capillary Gas Chromatography with Electron Capture Detection after Reduction with Lithium Aluminum Hydride and Derivatization with Heptafluorobutyric Anhydride

Neutral byproducts associated with the manufacture of illicit heroin are many and include meconin, 4-acetoxy-3,6-dimethoxyphenanthrene, N,O6-diacetylnorcodeine, 4-acetoxy-3,6-dimethoxy-5-<2-(N-methylacetamido)ethyl>phenanthrene, N,O3,O6-triacetylnormorphine, and 4-acetoxy-3,6-dimethoxy-8-<2-(N-metnylacetamido)ethyl>phenanthrene.These N- and O-acetylated impurities, and meconin, are easily isolated from the bulk heroin matrix, after which they are subjected to reduction with lithium aluminum hydride (LiAlH4) followed by derivatization with heptafluorobutyric anhydride (HFBA) in the presence of pyridine.The resultant haptafluorobutyryl (HFB) electrophiles are detected on-column at picogram (pg) levels by using capillary column gas chromatography/electron capture detection (CC/GC/ECD) in the splitless mode.The method is applicable for the in-depth analyses of crudely processed and highly refined heroin samples.

Discovery, synthesis, and bioactivity of bis(heteroaryl)piperazines. 1. A novel class of non-nucleoside HIV-1 reverse transcriptase inhibitors

A variety of analogues of 1-[4-methoxy-3,5-dimethylbenzyl]-4-[3- (ethylamino)-2-pyridyl]piperazine hydrochloride (U-80493E) were synthesized and evaluated for their inhibition of human immunodeficiency virus type 1 (HIV-1) reverse transcriptase (RT). Replacement of the substituted aryl moiety with various substituted indoles provided bis(heteroaryl)piperazines (BHAPs) that were 10-100-fold more potent than U-80493E. The pyridyl portion of the lead molecule was found to be very sensitive to modifications. Extensive preclinical evaluations of several of these compounds led to the selection of 1-[(5-methoxyindol-2-yl)carbonyl]-4-[3-(ethylamino)-2- pyridyl]piperazine methanesulfonate (U-87201E, atevirdine mesylate) for clinical evaluation.

3-(Oxazolo[4,5-b[pyridin-2-yl)anilides as a novel class of potent inhibitors for the kinetoplastid Trypanosoma brucei, the causative agent for human African trypanosomiasis

A whole organism high-throughput screen of approximately 87,000 compounds against Trypanosoma brucei brucei led to the recent discovery of several novel compound classes with low micromolar activity against this organism and without appreciable cytotoxicity to mammalian cells. Herein we report a structure-activity relationship (SAR) investigation around one of these hit classes, the 3-(oxazolo[4,5-b]pyridin-2-yl)anilides. Sharp SAR is revealed, with our most active compound (5) exhibiting an IC50 of 91 nM against the human pathogenic strain T.b. rhodesiense and being more than 700 times less toxic towards the L6 mammalian cell line. Physicochemical properties are attractive for many compounds in this series. For the most potent representatives, we show that solubility and metabolic stability are key parameters to target during future optimisation.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.COA of Formula: C9H6O3, you can also check out more blogs about496-41-3

Palladium catalyzed direct 3-arylation of benzofurans using low catalyst loadings

The palladium-catalyzed direct 3-arylation of benzofurans provides a cost-effective and environmentally attractive route for the preparation of 3-arylbenzofuran derivatives. The reactions were carried out using a wide variety of electronically and sterically diverse aryl or heteroaryl bromides with low catalyst loadings. In the presence of only 0.1-0.5 mol% catalyst, products in moderate to good yields were obtained. The aryl bromide reactants were able to tolerate a wide range of functionalities, such as acetyl, propionyl, formyl, ester, nitrile, trifluoromethyl, or fluoro groups. Higher yields were obtained using electron-deficient aryl bromides as reactants compared to using electron-rich aryl bromides. Functionalized benzofuran derivatives, bearing formyl or hydroxymethyl on C2, were also successfully employed.

A versatile palladium catalyst system was developed to effect the decarboxylative Heck coupling of a variety of arenecarboxylic acids with a wide range of olefins. The key to obtaining the efficient catalyst system is the use of 1-adamatanecarboxylic acid as additive. Alkyl-substituted olefins with coordinating groups were observed to provide significantly improved regioselectivity compared with other alkyl-substituted olefins lacking coordinating groups, and the acetate group of allylic ester was also tolerated in this reaction.
