Industrial-scale synthesis of eldecalcitol is described. AA highly diastereoselective epoxidation of p-methoxybenzyl (PMB) protected dienol at room temperature provides the key epoxide intermediate with a secondary hydroxyl group, which is alkylated with a triflate to set up all of the subunits at the C-1, C-2, and C-3 positions of the A-ring fragment. Selective protecting group manipulation followed by palladium-catalyzed cyclization then provides the A-ring synthon. The C/D-ring fragment is obtained by (1) direct C-H hydroxylation of Grundman’s ketone using in situ prepared trifluoropropanone dioxirane and (2) protection. Finally, the coupling of the A-ring with the C/D-ring fragment, global deprotection, and recrystallization provide the highly crystalline eldecalcitol.

Essential oils (EOs) from anise seeds (Pimpinella anisum) collected in the Algerian region were extracted by microwave-assisted hydrodistillation (MAHD) and hydrodistillation (HD). The oil yield (%), chemical composition, energetic consumption and the antimicrobial properties were evaluated of the obtained EO. The yields obtained by both processes were 2.81 +/- 0.01% for 90 minutes and 3.30 +/- 0.05% for 330 minutes for MAHD and HD, respectively. The determination of the chemical composition of EOs by GC-MS revealed the presence of a majority compound,trans-anethole 81.52% and 91.31% for MAHD and HD, respectively. The other main compounds present in the oils for MAHD and HD were, respectively: methyl chavicol (estragole) (0.63%-1.39%),cis-anethole (0.23%-0.34%), anisaldehyde (1.1%-1.57%), anisyl methyl ketone (0.28%-0.13%),trans-methyl isoellgenol (0.31%-0.17%),gamma-himachalene (0.5%-0.36%),trans-pseudoisoeugenyl 2-methylbutyrate (6.53%-2.53%) and epoxy-pseudoisoeugenyl 2-methylbutyrate (2.01%-0.56%). The EO obtained by MAHD detected other compounds, fenchone 0.41%, limonene 0.68%,cis-jasmolacatone extra C 0.41%,trans-isolongifolanone 0.2% and alpha-himachalene 0.16%. The energetic consumption by MAHD was significantly less than HD. Theoretical data from mathematical modelling were compared with practical data, and the coefficient of determination was between 0.93 and 0.97. The sensibility of bacterial strains to the essential oil obtained by MAHD is marked relatively to that obtained by HD, and for the sensibility of fungal strains, it was conserved. The MAHD process revealed a good yield of anise seeds EOs while reducing extraction time and energetic consumption. The EO extracted by this process revealed the presence of other compounds while improving antibacterial activity.

Small-ring heterocycles comprising pyrrole and pyrazole are well known for their rich biological properties. In this article, an efficient green sonochemical approach was designed for the synthesis of novel, fully substituted pyrroles connected to pyrazole scaffolds via a one-pot, four-component isocyanide-based sequential reaction. This reaction was carried out using various 5-amino-pyrazoles, aldehydes, dialkyl acetylenedicarboxylates and isocyanides for the synthesis of fully functionalized pyrroles with high chemoselectivity in the presence of a catalytic amount of PTSA center dot H2O, in good to excellent yields under ultrasound irradiation. This waste-free (-H2O) reaction exhibited a high atom economy and step economy via creating four new bonds, including two C-N and two C-C bonds, and the formation of two five-member heterocycles which are connected in a single operation. The mechanism of this four-component domino process involved sequential imination-dipolar cyclization-[1,5]-H shift reactions. The synthesized compounds possess interesting fluorescence features, and the bioactive scaffolds might attract great interest in the fields of clinical diagnostics and biomedical research in the future.

In this study, preparation, characterization and catalytic application of a novel core-shell structured magnetic Tiloaded phenylene-based nanoporous organosilica (Mag@Ti-NOS) nanocomposite are developed. The Mag@TiNOS was synthesized via cetyltrimethylammonium bromide (CTAB) directed co-condensation of tetramethoxysilane (TMOS), tetrabutyl orthotitanate (TBOT) and 1,4-bis(triethoxysilyl)benzene (BTEB) over Mag@ SiO2 under alkaline conditions. This nanocomposite was characterized by using FT-IR, EDX, PXRD, VSM, SEM, TEM, XPS, ICP and TGA techniques. These analyses showed a core-shell structure with high chemical and thermal stability for the designed material. The Mag@Ti-NOS nanocomposite was employed as an effective, powerful and recyclable catalyst in the synthesis of tetrahydrobenzo[b]pyrans in H2O at 50 degrees C under ultrasonic conditions. This catalyst was recovered and reused several times without significant decrease in efficiency and stability. The recovered catalyst was analyzed by FT-IR, PXRD and SEM to study its stability during reaction process.

Metal-free conjugated microporous polymers (CMPs) as visible-light active and recyclable photocatalysts offer a green and sustainable alternative to classical metal-based photosensitizers. However, the strategy for screening CMP-based heterogeneous photocatalysts has not been interpreted up to now. Herein, we present a general strategy for obtaining excellent solid photocatalysts, which is to implement bandgap engineering in the same series of materials. As a proof of concept, three conjugated porous materials containing benzo[1,2-b:3,4-b0:5,6-b00]trithiophene building blocks (BTT-CMP1, BTT-CMP2 and BTT-CMP3) were successfully constructed. They possess permanent porosity with a large specific surface area and excellent stability. By changing the linker between benzotrithiophene units, the bandgaps, energy levels and photoelectric performances including the absorption, transient photocurrent responses and photocatalytic performances of BTT-CMPs could be handily modulated. Indeed, BTT-CMP2 displayed the best catalytic activity for visible-light-induced synthesis of benzimidazoles among the three CMP materials, even higher than that of small molecule photocatalysts. As a metal-free photocatalyst, interestingly, the screened BTT-CMP2 also showed extensive substrate applicability and outstanding recyclability. Additionally, we have the opinion that this strategy will prove to be a guiding principle for screening superior CMP-based photocatalysts and broaden their application fields.

This report describes the development and optimization of the one-pot method for the synthesis of N-protected 1-aminoalkylphosphonium salts based on the three-component coupling of aldehydes and either amides, carbamates, lactams, imides, or urea in the presence of triarylphosphonium salts. The proposed strategy is very efficient and easy to carry out even on a larger scale (20 g) in any typical laboratory. Most reactions occur at temperatures between 50 and 100 degrees C in a short time (1-2 h) without requiring any catalyst, and simple workup procedures afford good to excellent yields. The exceptions are condensations with imides, which require much higher temperatures (150-170 degrees C) and longer reaction times (even 30 h). The possibility of carrying out the synthesis under solvent-free conditions (neat reactions) is also demonstrated. It is especially important for less reactive substrates (imides), and reactions required high temperature (or generally harsher conditions). Finally, we prove the developed one-pot methodology can be successfully applied for the synthesis of structurally diverse N-protected 1-aminoalkylphosphonium salts. Mechanistic studies showed the intermediate products of described couplings are 1-hydroxyalkylphosphonium salts, not N-hydroxyalkylamides, -imides, etc., as initially expected.

The crystal structures, Hirshfeld surface analysis and PIXEL calculations are reported for (E)-3-(4-methoxyphenyl)-1-(2-hydroxy-5-isoproproxyphenyl)prop-2-en-1-one, 1, and (E)-3-(3-methoxy-4-isopropoxyphenyl)-1-(2-hydroxy-4,6-diisoproproxyphenyl)prop-2-en-1-one, 2. Different sets of C-H…O, C-H…pi, off-set, face-to-face pi…pi and/or C=O…pi intermolecular interactions are displayed by each compound. Due to the bulk of the isoproproxy unit and the consequent steric hindrance in forming aggregates in the solid state, compounds 1 and 2 exhibit larger interplanar angles than do corresponding chalcones with methoxy units. The total stabilization energies of the crystal packing, E-tot distributed as Coulombic (E-coul), polarization (E-pol), dispersion (E-disp), and repulsion (E-rep) have been computed by PIXEL. For compound 1, six motifs (molecule pairs) and for compound 2, with two independent molecules in the asymmetric unit, thirteen motifs are identified by the PIXEL calculations to have energies, -E-tot, above the cut-offvalue of 10 kJ.mol(-1). For each of these motifs, the largest contributor to the E-tot value is the E-disp term, irrespective of the type(s) of interaction(s) connecting the two molecules, if any, in the motifs.
