Organocatalysis in the Synthesis of 1,2,3-Triazoyl-zidovudine Derivatives: Synthesis and Preliminary Antioxidant Activity

We describe herein the organocatalyzed synthesis and preliminary results of antioxidant activities of a range of 1,2,3-triazoyl-zidovudine derivatives. These hybrid compounds were synthesized in moderate to excellent yields by reacting zidovudine1with a variety of functionalized keto compounds2, such as beta-keto-esters, beta-diketones, beta-keto-amides, alpha-keto-nitriles, and beta-keto-sulfones, in the presence of a catalytic amount of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) (10 mol %). Furthermore, the synthesized compounds were screened for their in vitro antioxidant activity. Compounds3 a,3 d,3 g, and3 linhibited the formation of reactive oxygen species (ROS) and lipid peroxidation in the prefrontal cortex and hippocampus of mice with similar potency and efficacy.

Study of surface heterogeneity and nitrogen functionalizing of biochars: Molecular modeling approach

The functionality of biochar surfaces depends on the nature of the feedstock, pyrolysis temperature, and residence time. In this study, molecular modeling was used to determine the types of functionalization that could enhance adsorption and to pre-screen the target adsorbate for the sake of minimizing experimental time. The impact of a single functional group and interaction between them (including nitrile, methyl, ether, furan, carboxyl, hydroxyl, amine, and amide) on the adsorption of target adsorbate onto biochar was investigated. Among biochars inherent functional groups simulated, the lowest energy of adsorption (highest adsorption) occurred with carboxyl and hydroxyl for CO2 adsorption due to hydrogen bonding. The simulations showed adding amine/amide functional groups to the biochar surface enhanced CO2 adsorption, because of stronger bonding. The simulation results were compared against experimental results and the thermodynamic properties were satisfactorily matched. The overall heat of adsorption of H2S was lower than CO2, but the average Gibbs free energy was approximately the same, indicating CO2 could replace H2S in initial screening adsorption experiments for this type of biochar, reducing costs, risk and toxicity concerns of using H2S. This is an example of potentially how the models can be used to better design experiments. (C) 2020 Elsevier Ltd. All rights reserved.

Preparation of pyrrolin-2-ones and 4,5-dihydrodipyrrin-1-ones by oxidation of alpha-formylpyrroles and alpha-formyldipyrromethanes with hydrogen peroxide

Various substituted alpha-formylpyrroles and -dipyrromethanes have been oxidized by hydrogen peroxide under mild conditions to give pyrrolin-2-ones (2) and 4,5-dihydrodipyrrin-1-ones (4) with concomitant loss of the formyl substituent, thus extending the scope of this oxidation to dipyrromethanes. This makes the reaction especially useful for the preparation of bile pigments, for which the pyrrolinones and 4,5-dihydrodipyrrinones constitute important synthons. (C) 2000 Elsevier Science Ltd.

Studies on the oxidation of 2,2,4-trisubstituted 3-pyrrolines

As part of our studies directed towards a total synthesis of lactacystin, we have developed a reliable and environmentally acceptable method to oxidise 2,2,4-trisubstituted 3-pyrrolines to the corresponding 3-pyrrolin-2-ones. Several protocols were examined and the two-step (i) TPAP/NMO; (ii) sodium hypochlorite allylic oxidation was found to be the most satisfactory. Catalytic oxidation of the 3-pyrroline afforded the corresponding cyclic imine in high yield, and subsequent oxidation with NaOCl afforded the N-chloro-3-pyrrolin-2-one. The N-chloro-substituent was removed by a simple acid treatment. (C) 2002 Published by Elsevier Science Ltd.

Chiral pyrroloisothiochroman and pyrrolo[d]thiepine were obtained efficiently in four steps from N-alkylated maleimides via, successively, sulfurization, regioselective reduction followed by pi -cationic cyclination of the N-acyliminium ion intermediates. These latter, in addition, led to conjugate enamides as a consequence of the dehydration reaction. (C) 2001 Elsevier Science Ltd. All rights reserved.

Alkyne 1,1-Hydroboration to a Reactive Frustrated P/B-H Lewis Pair

The Mes(2)P-C equivalent to C-SiMe3 alkyne reacts with the borane H2B-Fmes by means of a rare 1,1-hydroboration reaction to give an unsaturated C-2-bridged frustrated P/B-H Lewis pair. Most of its reactions are determined by the presence of the B-H functionality at the FLP function and the activated connecting carbon-carbon double bond. It reduces carbon monoxide to the formyl stage. With nitriles it reacts in an extraordinary way: it undergoes a reaction sequence that eventually results in the formation of a P-substituted dihydro-1,2-azaborole derivative. Several similar examples were found. In one case a P-ylide was isolated that was related to an intermediate of the reaction sequence. It subsequently opened in an alternative way to give an alkenyl borane product.

The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules. In my other articles, you can also check out more blogs about 3446-89-7. HPLC of Formula: https://www.ambeed.com/products/3446-89-7.html.

The study of genotoxicity of two newly synthesized pyrrolinone derivatives on L5178Y mouse lymphoma and bone marrow cells

Genotoxic activity of two newly synthesized pyrrolinone derivatives (lactone (PTB) and lactame (PTP)) was studied both in vitro and in vivo. The substances were incubated with L5178Y mouse lymphoma cells for 4 h, then washed from the substances, and incubated for 18 h. PTP induced significantly increased number of micronuclei (MN) only at the highest dose used (1000 mug/ml). The 20-fold increase of the concentration of PTP led to 2.4-fold increase of the number of MN. PTP wasn’t toxic for lymphoma cells in the applied concentration range. In contrast, PTB induced significantly increased number of MN in lymphoma cells beginning from the concentration of 50 mug/ml and was toxic for lymphoma cells at concentrations of 500 mug/ml and higher. In the comet assay with L5178Y mouse lymphoma cells both substances were active at all concentrations used (PTP at concentrations of 50 mug/ml and 100 mug/ml, and PTB at concentrations of 100 mug/ml and 250 mug/ml). Acute toxicity and MN-inducing activity of compounds were studied on Swiss albino mice. PTB was substantially more toxic for mice than PTP (LD50 was 200 mg/kg and 370 mg/kg respectively). In mouse bone marrow polychromatic erythrocytes PTP induced significantly increased number of MN only at a dose equal to 1/2 of LD50. In contrast, PTB was mutagenic at all doses used -1/2, 1/5, and 1/10 of LD50. At equitoxic doses PTB induced more than 2-fold and 3.5-fold increased levels of MN compared with PTP (1/2 and 1/5 of LD50 respectively). The replacement of =NH group to =O group in chemical structure of pyrrolinone derivatives leads to substantial increase in acute toxicity for mice (1.85-fold) and MN induction activity both in vivo and in vitro.

Recent advances in C-CN and C-H bond activation of green nitrile (MeCN) for organo-complexation, cyanation and cyanomethylation

The use of green and inexpensive organic nitrile (MeCN) as a cyano and cyano-methyl source for organo-complexation, cyanation, and cyanomethylation is reviewed. In recent decade, a lot of developments have been made to realize the possibility of using a green cyanide source (MeCN) for cyanation, and this CN source has been used as, for example, a slow dosage cyanide source that could solve the problem of using metal cyanides (K-4[Fe(CN)(6)], Zn(CN)(2), KCN, CuCN, NaCN), which (1) tend to cause rapid deactivation of the catalyst and (2) are notoriously toxic, producing highly toxic HCN gas in reactions. In view of these problems, here we attempted to discuss new catalyst systems to achieve the cyanation of various aromatic hydrocarbons, such as aryl halides, aryl boronic acids, aryl carboxylic acids, indoles, diazoarenes, aryl alkynes, aryl sulfonamides, and directing group substituted arenes, under variety of reaction parameters. Moreover, acetonitrile is used as the carbon pro-nucleophile in C-C bond formation, which involves complications usually associated with the catalyst active mode or its resting state. This review demonstrates a set of innovations for practical usageviadirect complexation, cyanation and cyanomethylation methodologies.
