We describe an aerobic intramolecular dearomative coupling reaction of tethered phenols using a catalytic system consisting of a chromium-salen (Cr-salen) complex combined with a nitroxyl radical. This novel catalytic system enables formation of various spirocyclic dienone products including those unable to be accessed by previously reported methods efficiently under mild reaction conditions.

Background: Griseofulvin – a mold metabolite produced by Penisilium griseofulvum is known as an antifungal drug. Objective: Thus, the goal of this paper is the design and synthesis of new griseofulvin derivatives and evaluation of their antifungal activity. Methods: Forty-two new compounds were synthesized using classical methods of organic synthesis and evaluated for their antimicrobial activity by microdilution method. Results: All forty-two new compounds exhibited very good activity against eight tested micromycetes with MIC ranging from 0.0075-0.055 mg/ml and MFC from 0.02-024 mg/ml. All compounds exhibited better activity than reference drugs ketoconazole (7-42 times) and bifonazole (3-16 fold). The most promising was compound 15. The most sensitive fungal was found to be T. viride, while the most resistant, as was expected, was A. fumigatus. It should be mentioned that most of compounds exhibited better activity than griseofulvin. The molecular docking studies revealed that the most active compound have the same hydrophobic and H-bonding interactions with Thr276 residue observed for griseofulvin forming 3 hydrogen bonds while griseofulvin only one. In general, the molecular docking results coincide with experimental. Conclusion: Forty-two giseofulvin derivatives were designed, synthesized and evaluated for antimicrobial activity. These derivatives revealed good antifungal activity, better than reference drugs ketoconazole, bifonazole, and griseofulvin as well.

A new strategy is presented for enhancing the catalytic activity of cross-linked chitosan beads. More precisely, chitosan beads were cross linked with glutaraldehyde and then, vinyl functionalized. In the next step, the vinyl-functionalized beads were polymerized with the as-prepared 1-vinyl-3-butylimidazolium bromide to furnish polyionic liquid on beads. The resultant compositewas subsequently utilized as a metal-free catalyst for catalyzing some classic organic transformations, including Knoevenagel condensation reaction and syntheses of tetrahydrobenzo[b]pyrans and pyrano[2,3-d]pyrimidines in aqueous media under mild reaction conditions. It was found that the novel composite could efficiently promote all of the examined reactions to afford the corresponding products in high yields. Moreover, the catalyst exhibited high recyclability for all reactions. The comparative studies also approved that the activity of the composite was superior compared to cross-linked bead and polyionic liquid. (C) 2021 Elsevier B.V. All rights reserved.

A novel series of picarbutrazox-inspired oxadiazole hybrids was synthesized and the derivatives’ biological activity against phytopathogenic fungi was investigated. The molecules were designed by retaining the active fragment of tetrazolyl phenyloxime ether of lead compound picarbutrazox, while introducing the potentially active oxadiazole-derived fragment. Bioassay results revealed that some of the title compounds showed potent in vivo antifungal activities to control cucumber downy mildew. Therefore, this novel oxadiazole phenyloxadiazole derivative can be used as a potential antifungal agent to control cucumber downy mildew and other phytopathogenic fungi for crop protection.

The difficulties in the separation of products from the reaction mixture and the recovery of the organic cationic ionic liquids (OCILs) catalysts still need to be addressed. Post modification of the pyridine unit in the covalent organic framework (COF) via the formation of pyridinium salts with the chiral bromoacetate led to the chiral ionic COF with OCIL immobilized, which was utilized as a heterogeneous catalyst for asymmetric Henry reactions with high yield and excellent stereoselectivity.

Copper porphyrin-catalyzed construction of ether bond by cross-dehydrogenative coupling of sp [3] C-H bond with phenols bearing electron-withdrawing groups (EWG) was described for the first time. A broad range of substrates afforded different acetals in moderate to excellent yields with good functional group tolerance. The developed method is not only suitable for phenol substrates with ortho-directing groups, but also suitable for those phenol without ortho-directing groups. Significantly, a high turnover number (TON) up to 7300 was achieved in gram-level test. (C) 2020 Elsevier Ltd. All rights reserved.

Herein we report the generation of benzylic lithiums via an iodine-lithium exchange reaction on benzylic iodides performed in continuous flow using tBuLi as the exchange reagent. The resulting benzylic lithium species are trapped in situ by carbonyl electrophiles under Barbier conditions, resulting in benzylic secondary and tertiary alcohols. This flow procedure further allows the generation of highly reactive heterobenzylic lithium compounds, which are difficult to generate under batch conditions. A general scale-up was possible without further optimization.

High yield 3-hydroxy benzaldehyde-N-methyl 4-stilbazolium tosylate (3-HBST) was synthesized by optimizing the reaction temperature. High-quality bulk crystals of 3-HBST were grown by slow evaporation technique and spontaneous nucleation method, respectively. The crystal structure of 3-HBST was determined by single crystal X-ray diffraction (XRD) technique and belongs to monoclinic system. The defects of the 3-HBST crystals were observed by the synchrotron radiation X-ray topography. 3-HBST crystal remains stable until 305 degrees C, with a melting point of 214.1 degrees C from the TG-DTG and DSC techniques. The dielectric constant of 3-HBST crystal was also studied. The grown crystal had good optical transparency and the optical transmittance was investigated by UV-vis-NIR spectral analysis. Photoluminescence (PL) indicated green emission occurred at 478 nm. Based on the growth technical analysis and performance parameters measurements, 3-HBST crystal was verified to be a promising organic nonlinear optical crystal.

Two different hydrolysis strategies, namely acid hydrolysis (pH 0 and 3) and enzyme hydrolysis (Rapidase AR2000, beta-glucosidase, 5.6 nkat/mg), and the effect of hydrolysis time on the liberation of glycosidically bound volatiles from tamarillo (Solanum beaceum Cay.), were evaluated. Free and bound volatile profiles in tamarillo were also compared. Enzymatic hydrolysis was favoured for the liberation of aldehydes, esters, and terpenes. Harsh acidic hydrolysis (pH 0) was particularly effective at releasing C-13-norisoprenoids including 3-hydroxy-beta-damascone and 1,1,6-trimethyl-1,2-dihydronaphthalene (TDN), but those compounds cannot contribute to the pleasant odour. Moreover, the longer the duration of enzymatic hydrolysis, the higher was the concentration of alcohols, terpenes, benzenoids, ketones, and volatile phenols. On the other hand, 33 free and 49 bound volatiles were identified in tamarillo with a complementary profile: the major free volatiles were alcohols ((Z)-3-hexenol, 1-hexanol) and esters (methyl caproate, methyl butanoate and ethyl butanoate), while bound volatile compounds showed higher concentrations of benzenoids (benzyl alcohol and phenylethyl alcohol) and terpenes, including prenol, linalool and alpha-terpineol. Many glycosidically bound volatiles are available as aroma reservoirs in tamarillo, and to liberate these compounds during tamarillo-based product development, attention should be given to hydrolysis strategies and incubation time.
