We developed a facile and green one-pot synthetic method for substituted 1,3,5-triaryl-1,5-diketones by Claisen-Schmidt condensation following Michael addition reaction of aryl ketones and aryl aldehydes under a transition-metal-free condition. This convenient one-pot synthetic strategy has several advantages, including being transition-metal-free, having no extra additives or reagents, having a broad substrate scope, having a high isolated yield, having a minimum amount of base employment, having a shorter reaction time, use of cheap starting materials, cost-effectiveness, and being environment friendly. Some of the chemical structures of 1,5-diketones were confirmed by X-ray single-crystal diffraction analysis. The application of 1,5-diketones was demonstrated in the preparation of 2,4,6-triaryl pyridine derivatives under a catalyst-free system using ammonium acetate as a nitrogen source.

A novel mesoporous composite was prepared through the hybridization of cobalt-based metal-organic framework (Co-MOF) and covalent organic framework (COF) based on melamine and terephthaldehyde (Co-MOF/COF) and characterized by FT-IR, SEM, XRD, EDS, BET, and STA analyses. The resultant composite was utilized as a robust recoverable catalyst in the condensation of several aldehydes with malononitrile to produce benzylidenemalononitrile derivatives in 62-94% yields under solvent-free conditions at room temperature using 15 mg of the catalyst and 5-60 min of reaction. The examination of catalytic performance of designated Co-MOF/COF exhibited an outstanding activity for the Knoevenagel condensation in a very short time. The recoverability, reusability and durability of Co-MOF/COF have also been investigated under applied conditions.

Reported is the enantioselective total syntheses of mavacuran alkaloids, (+)- taberdivarine H, (+)- 16- hydroxymethyl- pleiocarpamine, and (+)- 16- epi- pleiocarpamine, and their postulated biosynthetic precursor 16- formyl- pleiocarpamine. This family of monoterpene indole alkaloids is a target of choice since some of its members are subunits of intricate bisindole alkaloids such as bipleiophylline. Inspired by the biosynthetic hypothesis, an oxidative coupling approach from the geissoschizine framework to form the N1 @ C16 bond was explored. Quaternization of the aliphatic nitrogen center was key to achieving the oxidative coupling induced by KHMDS/ I2 as it masks the nucleophilicity of the aliphatic nitrogen center and locks in the required cis conformation.

Background: The quinoline scaffold has been an attraction due to its pharmacological activities such as anti-HIV, anti-neoplastic, anti-asthmatic, anti-tuberculotic, anti-fungal, and anti-bacterial. Objective: The designed quinoline-3-carboxylate derivatives were synthesized through a two-step reaction and evaluated for antiproliferative activity against MCF-7 and K562 cell lines. Methods: Synthesized compounds were characterized by modern analytical techniques like NMR, 2DNMR, mass. and IR. Moreover, the purity of compounds was analyzed through the HPLC. In the progress of biological results, all synthesized compounds were evaluated for antiproliferative activity against MCF-7 and 1562 cell lines. Results: The synthesized compounds exhibited micromolar inhibition in all over the ranges, however, some of the compounds showed better activity than the standard anticancer drug such, as 4m and 4n with the IC50 value of 0.33 mu M against the MCF-7 cell line, and the compounds 4k and 4m showed potential activity against the K562 cell line with the IC50 value of 0.28 mu M. The anti-cancer activities of compounds were found to be thmugh the up-regulation of intrinsic apoptosis pathways. Conclusion: The biological data of all compounds in both cell lines were utilized for the structural activity relationship of the quinoline-3-carboxylate pharmacophore. The active lead was further validated through rigorous in silico studies for the drug-likeness (QED) and Absorption, Distribution, Metabolism, Excretion, and Toxicity (ADMET) properties. Here in the present research is utilized for the demonstration of an important pharmacophore, which could be utilized for further development to become a lead as an anticancer agent with minimal toxicity.

A new synthesis of treprostinil is described using a plug flow reactor in two of the key steps. First, a Claisen rearrangement reaction is described in scaled flow at multigram amounts. Yields and selectivity of this step are sharply improved compared to those from previous syntheses. Second, the key Pauson-Khand reaction in flow is described under catalytic conditions with 5 mol% of cobalt carbonyl and only 3 equiv. of CO. Scaling up of this reaction safely ensures a good yield of an advanced intermediate which is transformed into treprostinil in three steps. Other improvements are the introduction of the carboxymethyl chain into the phenol from the beginning to reduce the protection-deprotection steps. The synthesis is completed in 14% global yield after 12 linear steps from (S)-epichlorhydrin.

Mesoporous AlSBA-15 catalysts (n(Si)/n(Al)ratios of 41, 129 and 210) were synthesized by sol-gel method. These materials were characterized by XRD, N(2)sorption, FTIR, TPD-NH3, FESEM, EDX, and TEM analysis. XRD analysis of AlSBA-15 catalysts confirmed the existence of well-ordered crystalline structure havingp6mmsymmetry. N(2)sorption isotherm of AlSBA-15 catalysts showed a type IV adsorption isotherm with H1 hysteresis loops. SEM analysis of AlSBA-15 (41) indicated worm-like particle morphology with a size range of 3 mu m with co-occurrence of smaller particles of size ca. 1 mu m. TEM analysis of AlSBA-15 (41) showed existence of uniform array of tubular nano-channels. The catalytic application of AlSBA-15 catalysts was tested on industrially important chalcones synthesis via Claisen-Schmidt condensation reaction in environment friendly approach. The reaction parameters such as time, temperature,n(Si)/n(Al)ratio, catalyst amount, and catalyst stability were investigated. AlSBA-15 (41) catalyst showed an excellent catalytic performance with 98% 1-tetralone conversion with 100% selectivity of compound 1c (91% yield) within 120 min AlSBA-15 (129) and AlSBA-15 (210) catalysts. The anti-oxidant activity of the synthesised chalcones were investigated by various in-vitro procedures, including radical scavenging potentials-1, 1-diphenyl-2-picryl-hydrazil, hydrogen peroxide scavenging, and ferric reducing potential assay. The new chalcone derivatives synthesised in this work showed a very good antioxidant activity and some were found to be more active than the parent chalcones, (E)-3-(4-hydroxy-3-methoxyphenyl)-1-phenylprop-2-en-1-one (compound 8c), and standard antioxidant (curcumin).

The alkylation of 1H-tetrazole, 5-methyl-1H-tetrazole, and 5-phenyl-1H-tetrazole with primary, secondary, and tertiary alcohols, including benzylic and allylic ones, have been studied in 1,2-dichloroethane in the presence of boron trifluoride-diethyl ether complex. Neither primary nor secondary saturated alcohols alkylated tetrazoles in the given system. Tertiary alcohols suchtert-butyl alcohol and adamantan-1-ol reacted with unsubstituted and 5-substituted tetrazoles to give 70-85% of the corresponding 2-alkyl-5-R-tetrazoles with high regioselectivity. The alkylation of 1H-tetrazole with benzyl alcohol afforded 55% of 2-benzyl-2H-tetrazole as the only product. The alkylation of 1H-tetrazole with various allylic alcohols led to the formation of mixtures of 2-alkyl-2H-tetrazoles with isomeric alkyl substituents.

Several diastereoisomeric polyesters bearing vicinal stereogenic centers in the backbone were synthesized to investigate the influence of diastereoisomerism on the properties of polymers. To hamper the free rotation of the C-sp(3)-C-sp(3) single bond between the stereogenic centers, bisphenol monomers containing vicinal CF3 moieties were designed and synthesized, wherein the CF3 group acts not only as a conformational stabilizer but also as a probe to provide information on stereoconfiguration. X-ray single-crystal structure and density functional theory (DFT) calculations indicate that the antimonomer tends to adopt a linear and extended configuration, whereas the most stable conformation for its diastereoisomer is kinked. These geometries resemble those possessed by the E and Z 1,2-disubstituted alkenes. The polymers based on these isomeric monomers display distinct glass transition state temperature (T-g), crystallinities, mesoscopic morphology, and hydrophobicity, which can be attributed to the different polymer chain arrangement in the solid state. These observations support our hypothesis to utilize aliphatic moieties bearing vicinal stereogenic centers to mimic the geometry of the E and Z olefinic units, which serves as a new strategy to finely tune the polymer

The development of earth abundant 3d metal-based catalysts continues to be an important goal of chemical research. In particular, the design of base metal complexes for reductive amination to produce primary amines remains as challenging. Here, we report the combination of cobalt and linear-triphos (bis(2-diphenylphosphinoethyl)phenylphosphine) as the molecularly-defined non-noble metal catalyst for the synthesis of linear and branched benzylic, heterocyclic and aliphatic primary amines from carbonyl compounds, gaseous ammonia and hydrogen in good to excellent yields. Noteworthy, this cobalt catalyst exhibits high selectivity and as a result the -NH2 moiety is introduced in functionalized and structurally diverse molecules. An inner-sphere mechanism on the basis of the mono-cationic [triphos-CoH](+) complex as active catalyst is proposed and supported with density functional theory computation on the doublet state potential free energy surface and H-2 metathesis is found as the rate-determining step.
