The reduction of cage ketoximes under Schwenk–Papa reaction conditions was studied to establish that the d,l, d- and l-camphor oximes are smoothly reduced to the corresponding amines in high yields. At the same time, d,l-norcamphor and adamantan-2-one oximes undergo partial catalytic deoximation to form a mixture of the corresponding amines and alcohols.
Synthesis and biological evaluation of phenylpropanoid derivatives
Liu, Sheng,Li, Yubin,Wei, Wanxing,Wei, Jingchen
, p. 1074 - 1086 (2016/07/06)
In this work, a series of oxime ether phenylpropanoid derivatives were synthesized. Their anti-hepatitis B virus (HBV) activity in HepG 2.2.15 cells was determined, and anti-cancer potential against three human cancer cell lines was evaluated. All the synthesized derivatives showed great efficiency against HBV. Compound 4d demonstrated the most effective anti-HBV activity, performing strong potent inhibitory not only on the secretion of HBsAg (IC50?=?50.45?μM, SI?=?9.18) and HBeAg (IC50?=?50.11?μM, SI?=?9.24), but also on the HBV DNA replication (IC50?=?51.80?μM, SI?=?8.94). Besides, the synthetic compounds also displayed obvious anti-cancer activity. Moreover, the docking study of all synthesized compounds inside the related protein active site was conducted to explore the molecular interactions and a molecular target for activity using a MOE-docking technique. This study identified a new class of potent anti-HBV and anti-cancer agents.

An acceptor-free catalysis protocol for the deoximation of ketoximes and aldoximes using RuCl3 as the catalyst has been developed. Under the optimized conditions, various oximes were converted to ketones and nitriles with excellent isolated yields.

In alternative embodiments, the invention provides nucleophilic hydroxyimino- acetamido alkylamine antidotes that cross the blood-brain barrier (BBB) to catalyze the hydrolysis of organophosphate (OP)-inhibited human acetylcholinesterase (hAChE) in the central nerve system (CNS). The hydroxyimino-acetamido alkylamines of the invention are designed to fit within AChE active center gorge dimensions, bind with reasonable affinity, and react with the conjugated phosphate atom in the gorge. The hydroxyimino- acetamido alkylamines of the invention are also designed to possess ionization states that govern affinity and reactivity for the two linked hAChE re-activation steps. In alternative embodiments, the invention provides pumps, devices, subcutaneous infusion devices, continuous subcutaneous infusion devices, infusion pens, needles, reservoirs, ampoules, a vial, a syringe, a cartridge, a disposable pen or jet injector, a prefilled pen or a syringe or a cartridge, a cartridge or a disposable pen or jet injector, a two chambered or multi- chambered pump, a syringe, a cartridge or a pen or a jet injector, comprising a compound of the invention.
Oxidation of primary amines to oximes with molecular oxygen using 1,1-diphenyl-2-picrylhydrazyl and WO3/Al2O3 as catalysts

The oxidative transformation of primary amines to their corresponding oximes proceeds with high efficiency under molecular oxygen diluted with molecular nitrogen (O2/N2 = 7/93 v/v, 5 MPa) in the presence of the catalysts 1,1-diphenyl-2-picrylhydrazyl (DPPH) and tungusten oxide/alumina (WO3/Al2O3). The method is environmentally benign, because the reaction requires only molecular oxygen as the terminal oxidant and gives water as a side product. Various alicyclic amines and aliphatic amines can be converted to their corresponding oximes in excellent yields. It is noteworthy that the oxidative transformation of primary amines proceeds chemoselectively in the presence of other functional groups. The key step of the present oxidation is a fast electron transfer from the primary amine to DPPH followed by proton transfer to give the α-aminoalkyl radical intermediate, which undergoes reaction with molecular oxygen and hydrogen abstraction to give α-aminoalkyl hydroperoxide. Subsequent reaction of the peroxide with WO3/Al2O3 gives oximes. The aerobic oxidation of secondary amines gives the corresponding nitrones. Aerobic oxidative transformation of cyclohexylamines to cyclohexanone oximes is important as a method for industrial production of ε-caprolactam, a raw material for Nylon 6.

Chlorination of cyclic and linear ketone oximes with aqueous H 2O2/HCl in a two-phase dichloromethane-water system selectively affords gem-chloronitroso compounds in yields of up to 94%. One-pot oxidation of the resulting gem-chloronitroso compounds with peracetic acid, prepared in situ, gives gem-chloronitroalkanes and cycloalkanes in yields of up to 82%. The advantages of the method are that it is facile and environmentally benign and does not require gaseous chlorine. Georg Thieme Verlag Stuttgart.
