Synthesis and Transformation of Triterpenoids with a beta-Ketonitrile Fragment in Five-Membered Ring A

Triterpenoids with a beta-ketonitrile group in five-membered ring A were synthesized via intramolecular oxonitrile cyclization of C-3 methyl esters of 1-cyano-substituted 2,3-seco-triterpene acids. The intramolecular cyclization to form the triterpene ketonitriles and subsequent reduction of the oxo groups to give C-1 and C-3 substituents in the beta-orientation were confirmed to be stereoselective. Alkaline hydrolysis of the ketonitriles reduced the cyano groups to form the corresponding 3-oxo-2-nor-derivative while reduction and acylation of the beta-hydroxynitrile formed an alpha,beta-alkenenitrile fragment in the triterpenoid five-membered ring A.

Facile Amberlyst A-21 catalyzed access of beta-hydroxynitriles via epoxide opening in water

beta-Hydroxynitriles are essential intermediates in the synthesis of diverse bioactive compounds and clinical drugs. One of the precursor reactions to these intermediates is the opening of an epoxide ring with a cyanide nucleophile. In the present study, we report a milder and safer route to beta-hydroxynitriles employing recyclable, Amberlyst A-21 resin in the ring-opening of epoxides with acetone cyanohydrin in water. A diverse range of substrates (fifteen), including aromatic epoxides, phenoxy epoxides, non-terminal, and terminal aliphatic epoxides, are investigated under the optimized conditions to afford the desired beta-hydroxynitriles in good to excellent yield. In addition to this, the recyclability of the Amberlyst A-21 resin is also successfully demonstrated. This relatively safer methodology has the potential to be explored in other organic transformations. (C) 2020 The Authors. Published by Elsevier B.V. on behalf of King Saud University.

Efficient construction of diverse 3-cyanoindoles under novel tandem catalysis

A novel and rapid construction of 3-cyanoindoles by palladium-catalyzed tandem reactions has been developed. N-H free unprotected, N-alkyl and N-aryl 3-cyanoindoles are obtained with good to excellent yields. The usefulness of this synthetic approach is further demonstrated by the successful synthesis of practical compounds such as the therapeutic estrogen receptor ligand A precursor. Mechanism study shows that the tandem catalysis exploits a Suzuki cross-coupling with subsequent base-induced isoxazole fragmentation, followed by the aldimine condensation.

Polymerization mechanism of 4-APN and a new catalyst for phthalonitrile resin polymerization

The widely used catalysts for phthalonitrile (PN) resin polymerization are aromatic compounds containing -NH2 because of their high catalytic performances. However, the catalytic mechanisms of these catalysts are not very clear. To understand the mechanisms of them, the widely used autocatalytic catalyst 4-(4-aminophenoxy)-phthalonitrile (4-APN) was studied in this paper. The polymerization process of 4-APN was tracked by a multi-purpose method, and ammonia gas was detected during the cross-linking processing for the fist time. Combined with the online IR results of the curing process of 4-APN, the mechanism of ammonia generation was newly proposed. Based on this mechanism, a new catalyst selection strategy was promoted, which is different from the traditional approach to catalyst selection for PN resin polymerization. According to the new strategy, 1,3-diiminoisoindoline (1,3-DII) was selected as a novel catalyst. The results showed that the new catalyst could not only effectively catalyze the polymerization of PN resin, but also has a lower curing temperature than that of organic amine catalysts and can eliminate the release of ammonia gas and the voids in the products caused thereby. Therefore, the results of this study will give important enlightenment to the development of PN catalysts and the development of PN.

Ethanol amine functionalized electrospun nanofibers membrane for the treatment of dyes polluted wastewater

This study investigated adsorption kinetics, adsorption equilibrium, and adsorption isotherm of three dyes [i.e., methylene blue (MB), rhodamine-B (RB), and safranin T (ST)] onto polyacrylonitrile (PAN) and ethanolamine (EA) grafted PAN nanofibers (NFs) membranes (EA-g-PAN). The membranes were characterized by field emission scanning electron microscopy (FE-SEM), Fourier-transform infrared spectroscopy (FT-IR) spectroscopy, and Brunauer-Emmet-Teller (BET). FE-SEM showed a smooth morphology for the NFs before and after grafting, while FT-IR confirmed EA grafting into the nitrile group of PAN. The grafting percentage with no change in the physical nature of the membrane was 12.18%. The nitrogen adsorption-desorption isotherms for PAN and EA-g-PAN NFs membranes were similar and classified as a Type IV according to the International Union of Pure and Applied Chemistry. The surface area, pore-volume, and pore size of the EA-g-PAN increased to 21.36 m(2) g(-1), 0.16 cm(3) g(-1), and 304.93 angstrom, respectively. The pores were cylindrical mesopores with bimodal openings, which means that pores were open at both ends. The adsorption of the MB, RB, and ST dyes onto the PAN and EA-g-PAN NFs membranes leveled off at similar to 60 min. The adsorption kinetics showed good fitting to pseudo-second-order kinetic model and multi-step diffusion process. The order of the dye adsorption was PAN < EA-g-PAN. The data were fitted to Langmuir and Freundlich models. The correlation coefficient (r(2)) for Langmuir ranged from 0.940 to 0.995, whereas that for Freundlich ranged from 0.941 to 0.998. After adsorption, FTIR only showed hydrogen bonding between the dyes and the membrane. The reusability experiments showed max desorption for MB (94%), RB (92%), and ST (85%). The EA-g-PAN NFs membrane showed potential for the removal of organic pollutants from the environment. The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

Nickel-Catalyzed Migratory Hydrocyanation of Internal Alkenes: Unexpected Diastereomeric-Ligand-Controlled Regiodivergence

A regiodivergent nickel-catalyzed hydrocyanation of a broad range of internal alkenes involving a chain-walking process is reported. When appropriate diastereomeric biaryl diphosphite ligands are applied, the same starting materials can be converted to either linear or branched nitriles with good yields and high regioselectivities. DFT calculations suggested that the catalyst architecture determines the regioselectivity by modulating electronic and steric interactions. In addition, moderate enantioselectivities were observed when branched nitriles were produced.

Synthesis and characterization of epoxidized neem oil: A bio-derived natural processing aid for elastomer

Low cost and environment-friendly bio-oils are gaining market value as a plasticizer for elastomeric compounds. Unsaturated triglycerides of bio-oils can be easily modified in various ways, like epoxidation, esterification, and so on. In the present work, 15 mole percentage of the total double bond content of the neem oil (NO) was epoxidized by acetic acid-hydrogen peroxide system to synthesize epoxidized neem oil (ENO). NO and ENO were characterized by nuclear magnetic resonance spectroscopy, Fourier transform infrared spectroscopy and differential scanning calorimetry. The effect of ENO on the properties of nonpolar styrene butadiene rubber (SBR) and polar nitrile rubber (NBR) was investigated. Tear strength (69.9 N/mm), abrasion resistance index (ARI) (68.2) and hardness (64 shore A) of the SBR/ENO compound were comparable to the compound containing total distillate aromatic extract (TDAE) (values: 70.8 N/mm, 68.0 and 64 shore A respectively). Tensile strength and ARI of conventional NBR/dioctyl phthalate (DOP) compound were 24.9 MPa and 107 respectively, whereas NBR/ENO compound showed improved tensile strength (26.9 MPa), and ARI (138). Tear strength (83.4 N/mm) and hardness (74 shore A) of NBR/ENO were comparable to the tear strength (83.5 N/mm) and hardness (74 shore A) of NBR/DOP compound. Hence, the multifunctional additive property of ENO makes it a cheap and sustainable replacement of TDAE and DOP.

Mechanically robust and thermally insulating polyarylene ether nitrile with a bone-like structure

Inspired by the excellent mechanical performance of bone materials characterized by compact shell and porous core, this study proposes a lightweight, mechanically robust, and thermal-insulating polyarylene ether nitrile (PEN) with a bone-like structure. The supercritical fluid technique was applied to provide PEN with two types of tunable bone-like structures, which makes it simple to manipulated under supercritical treatment conditions. Depending on different bone-like microstructures, their tensile strength can reach up to 75 MPa with the impact strength range of 50-190 KJ/m2. Notably, the impact strength of PEN foam with a saturation time of 4 his 1.6% higher than that of pure PEN. Furthermore, lightweight PEN foams capable of thermal insulation and their conductivity can reach 0.06 W/m.K without compromising the actual mechanical performance. These lightweight PENs with a remarkable performance in thermal insulation and mechanical robustness show a massive potential in automobile application for effectiveness in energy conservation and reducing air pollution. Based on this experiment, a new method is proposed to prepare biomimetic bone-like materials. (c) 2020 The Author(s). Published by Elsevier Ltd.
