Solvent free synthesis of dihydropyrano[3,2-b]chromenediones was formulated via multicomponent reactions of kojic acid, dimedone and several substituted aromatic aldehydes catalyzed with BCl3. Reactions progressed efficiently and the corresponding heterocyclic products were obtained in good to high yields within short period. The developed protocol is one of the better and efficient alternative methods for the synthesis of dihydropyrano[3,2-b]chromenediones. The simple reaction procedure, easy separation of products, radially available catalyst are certain benefits of this reported protocol.

We have developed a supramolecular (close form) [2]pseudorotaxane polymer containing the green-emissive (lambda(em) = 523 nm) BODIPY-based pillar[5]arene host and the non-emissive spiropyran (SP)-based cyano guest (close form), which can be converted to a red-emissive (lambda(em) = 630 nm) merocyanine (MC)-based guest (open form) upon UV exposure as well as turned into a bi-fluorophoric host-guest polymer with ratiometric PL emission of Forster resonance energy transfer (FRET) behavior in THF/water solution (60% H2O, v/v). The equal host-guest molar ratio and the formation of the [2]pseudorotaxane polymer can be further verified using H-1 NMR titration, Job’s plot analysis, DOSY and ITC experiments. Hence, the bi-fluorophoric host-guest (with the MC open form) polymer possessed the highest red-emission of the MC acceptor, which was also confirmed using TRPL measurements to possess the shortest lifetime of 0.37 ns and the best FRET efficiency of 83.5%. Since the MC unit could react with CN- to induce a non-emissive quenching process, the mono-fluorophoric guest would show turn-off PL behavior and detect cyanide ions with a corresponding limit of detection (LOD) value of 0.94 mu M. In comparison, the optimal LOD value of 0.48 mu M toward CN- anion could be achieved by our bi-fluorophoric host-guest polymer via the FRET-OFF process. Therefore, cyanide detection and cell viability tests using the open form of the [2]pseudorotaxane polymer suggest useful bio-imaging applications in living cells.

Novel sulfonated carbon-coated magnetic nanoparticles (SCCMNPs; Fe3O4@C@OSO3H) were designed, synthesized, characterized, and applied as an efficient nanocatalyst for green synthesis of coumarin derivatives through Pechmann condensation. The Fe3O4@C@OSO3H was manufactured through a simple and inexpensive two-step procedure and characterized by FTIR, EDX, XRD, SEM, TEM, DLS, VSM, and TGA techniques. It was identified as an efficient heterogeneous catalyst in the Pechmann condensation of phenol derivatives and beta-ketoesters, leading to high-yield coumarin derivatives under solvent-free conditions. The Fe3O4@C@OSO3H removed after reaction finishing point by an external magnet, and it was reused fifteen times at the same conditions. Besides, theoretical studies were carried out using B3LYP/6-311++G(d,p) to more consideration of the reaction mechanism. The study of the frontier molecular orbitals, NBO atomic charges, molecular electrostatic potential of reactants, as well as Pechmann condensation mechanism was known very useful in suitable reactant choice. The reaction was performed through the electrophilic attack, dehydration, and trans-esterification, respectively. [GRAPHICS] .

We report the synthesis of the first transplatin-BODIPY conjugates for application in photodynamic therapy (PDT). The distyryl BODIPYs containing two iodine atoms were designed to absorb in the red region, easily undergo intersystem crossing for efficient singlet oxygen generation, and additionally offer the possibility for coordination with mono-activated transplatin. We were able to demonstrate that coordination of the BODIPYs with a mono-activated transplatin increases the phototoxic index of the photosensitizers significantly, giving rise to highly phototoxic distyryl BODIPY derivatives, of which one was shown to have the highest ever reported phototoxic index against any cell line. Furthermore, the photophysical mechanism of singlet oxygen generation in distyryl BODIPYs undergoing intramolecular charge transfer was studied experimentally and using time-dependent density functional theory.

Aurone-derived azadienes are well-known four-atom synthons for direct [4 + n] cycloadditions owing to their s-cis conformation as well as the thermodynamically favored aromatization nature of these processes. However, distinct from this common reactivity, herein we report an unusual formal migrative annulation with siloxy alkynes initiated by [2 + 2] cycloaddition. Unexpectedly, this process generates benzofuran-fused nitrogen heterocyclic products with formal substituent migration. This observation is rationalized by less common [2 + 2] cycloaddition followed by 4 pi and 6 pi electrocyclic events. DFT calculations provided support to the proposed mechanism.

An efficient synthesis of 4-arylidene-3-alkylisoxazole-5(4H)-ones has been implemented via the three-component cyclocondensation of aryl(heteroaryl)aldehydes with hydroxylamine hydrochloride and beta-ketoesters. The potassium 2,5-dioxoimidazolidin-1-ide has been introduced as the new organocatalyst to facilitate this heterocyclization. In the current process, three starting materials, including substituted benzaldehydes/heterocyclic aromatic aldehydes, hydroxylamine hydrochloride, and ethyl acetoacetate/propyl acetoacetate/butyryl acetoacetate have been successfully used to synthesize the number of substituted isoxazole-5-(4H)-ones in good to high yields in ethylene glycol as a green reaction medium at 80 degrees C. The low catalyst loading is also a main advantage over some reported catalysts.

The multicomponent reaction between tetronic acid (1), 2-aminoanthracene (2) and aromatic aldehydes (3) and the subsequent addition of DDQ produced a series of naphtho [2,3-f]quinoline lactone derivatives (5) in good yield. UV-Vis and fluorescence spectra of these derivatives are described. The optical absorption and emission properties of the compounds were studied in different solvents and pH. The results show that the naphthoquinoline derivatives have emission bands of 453-517 nm and one of them, compound 5d, had an unexpected bathochromic shift (597 nm) caused by an excited-state intramolecular proton transfer (ESIPT). The luminescent properties of 5d in different solvents and pH, although preliminary, indicate the potential use of this compound as a chemical sensor.

Recommanded Product: 3-(Trifluoromethyl)phenol. I found the field of Chemistry very interesting. Saw the article Pummerer Synthesis of Chromanes Reveals a Competition between Cyclization and Reductive Chlorination published in 2019, Reprint Addresses Gamba-Sanchez, D (corresponding author), Univ Andes, Dept Chem, Lab Organ Synth Bio & Organocatalysis, Cra 1 18A-12 Q 305, Bogota 111711, Colombia..

The competition between an unprecedented reductive chlorination and the Pummerer reaction was studied and applied to the synthesis of benzofused oxygen heterocycles including 3-aminochromanes and in the intramolecular chlorination of activated aromatic rings. The use of (COCl)(2) as a Pummerer activator showed substantial activity, producing alpha-chlorinated sulfides that can undergo Pummerer-Friedel-Crafts cyclization. If the aromatic ring has electron-donating groups in position three, then the reaction follows a different pathway, yielding the reductive chlorination products, where the chlorine atom comes from a sulfonium salt.
