Regioselectivity is a crucial issue in Baeyer-Villiger (BV) oxidation. To date, few reports have addressed asymmetric BV oxidation of 3-substituted cycloketones due to the high difficulty of controlling regio- and stereoselectivity. Herein, we report the asymmetric BV oxidation of 3-substituted and meso-disubstituted cycloketones with chiral N,N ‘-dioxide/Sc(iii) catalysts performed in three ways: classical kinetic resolution, parallel kinetic resolution and desymmetrization. The methodology was applied in the total and formal synthesis of bioactive compounds and natural products. Control experiments and calculations demonstrated that flexible and adjustable catalysts played a significant role in the chiral recognition of substrates.

A convergent strategy for the synthesis of multi-substituted pyridines is described. Vinylallenes combine with commercially available arylsulfonyl cyanides in Diels-Alder cycloadditions to generate isopyridine cycloadducts that are converted to pyridines upon further heating or addition of a base. The 2-sulfonylpyridine products undergo nucleophilic aromatic substitution reactions with oxygen and carbon nucleophiles to provide access to a variety of highly substituted pyridines.

A series of novel chalcone derivatives containing a thiophene sulfonate group were designed and synthesized. The structures of all title compounds were determined by H-1-NMR, C-13-NMR and HRMS. Antibacterial bioassays indicated that, compound 2l demonstrated excellent antibacterial activities against Xanthomonas axonopodis pv. citri (Xac), with an EC50 value of 11.4 mu g mL(-1), which is significantly superior to those of bismerthiazol (BT) (51.6 mu g mL(-1)) and thiodiazole-copper (TC) (94.7 mu g mL(-1)). Meanwhile, the mechanism of action of compound 2l was confirmed by using scanning electron microscopy (SEM). In addition, compound 2e showed remarkable inactivation activity against Tobacco mosaic virus (TMV), with an EC50 value of 44.3 mu g mL(-1), which was superior to that of ningnanmycin (120.6 mu g mL(-1)). Microscale thermophoresis (MST) also showed that the binding of compounds 2e and 2h to Tobacco mosaic virus coat protein (TMV-CP) yielded K-d values of 0.270 and 0.301 mu mol L-1, which are better than that of ningnanmycin (0.596 mu mol L-1). At the same time, molecular docking studies for 2e and 2h with TMV-CP (PDB code: ; 1EI7) showed that the compound was embedded well in the pocket between the two subunits of TMV-CP in each case. These results suggested that chalcone derivatives containing a thiophene sulfonate group may be considered as activators in the design of antibacterial and antiviral agents.

The chalcone derivatives 3a-d reacted with either malononitrile or ethyl cyanoacetate in ethanol in the presence of catalytic amount of ammonium acetate in an oil bath at 120 degrees C to give the Knowevenagel condensation products 5a-h. The latter compounds reacted with hydrazine hydrate and afforded the 4H-pyrazole derivatives 7a-h, respectively. The reaction of compounds 7a-h with ethyl cyanoacetate in dimethylformamide under refluxing condition afforded the cyanoacetamido derivatives 8a-h, respectively. When compounds 8a-h reacted with elemental sulfur and either of malononitrile or ethyl cyanoacetate in ethanol containing triethylamine, the thiophene derivatives 9a-h and 10a-h, respectively, were obtained. The structure of the newly synthesized compounds was established by the analytical and spectral data. All the newly synthesized compounds were evaluated against the six cancer cell lines: A549, HT-29, MKN-45, U87MG, and SMMC-7721 and H460. Compounds 3c, 5h, 7g, 7h, 8f, 9e, 9g, and 10g were selected to examine their Pim-1 kinase inhibition activity as these compounds showed high inhibition toward the c-Met kinase and the tested cancer cell lines. Furthermore, compounds 3b, 3c, 5g, 5h, 7f, 7g, 7h, 8e, 8f, 8g, 8h, 9e, 9f, 9g, 9h, 10g and 10h were selected to be tested for pan-assay interference compounds analysis (PAINS).

Terpenoid derivatives, which contain a preserved carane system in their structure, exhibit a broad spectrum of biological activities. Among them, we can distinguish insecticides, structures with pharmacological application etc. In the presented paper, the substrate – (-)-cis-caran-trans-4-ol was transformed using the reactions of typical organic synthesis to obtain novel derivatives. Most importantly, bromolactone ((-)-(1R,4R,6S)-2′-(bromomethyl)-4,7,7-trimethylspiro[bicyclo[4.1.0]heptan-3,3′-furan]-5′(4’H)-one) with the preserved carane system was synthesized. This bromolactone was tested for antifeedant activity against the lesser mealworm, Alphitobius diaperinus Panzer, and peach potato aphid (Myzus persicae). In addition, its moderate antibacterial activity was observed against the Bacillus subtilis strain (with Minimal Inhibitory Concentration of 200 mu g/mL).

To improve the properties of mesoporous carbon (MC), used as a catalyst support within electrodes, MC fibers (MCFs) were successfully synthesized by combining organic-organic self-assembly and electrospinning deposition and optimizing heat treatment conditions. The pore structure was controlled by varying the experimental conditions. Among MCFs, MCF-A, which was made in the most acidic condition, resulted in the largest pore diameter (4-5 nm), and the porous structure and carbonization degree were further optimized by adjusting heat treatment conditions. Then, since the fiber structure is expected to have an advantage when MCFs are applied to devices, MCF-A layers were prepared by spray printing. For the resistance to compression, MCF-A layers showed higher resistance (5.5% change in thickness) than the bulk MC layer (12.8% change in thickness). The through-plane resistance was lower when the fiber structure remained more within the thin layer, for example, +8 m omega for 450 rpm milled MCF-A and +12 m omega for 800 rpm milled MCF-A against the gas diffusion layer (GDL) 25BC carbon paper without a carbon layer coating. The additional advantages of MCF-A compared with bulk MC demonstrate that MCF-A has the potential to be used as a catalyst support within electrodes in energy devices.

Described is a general method for the installation of a minimal 6-methyltetrazin-3-yl group via the first example of a Ag-mediated Liebeskind-Srogl cross-coupling. The attachment of bioorthogonal tetrazines on complex molecules typically relies on linkers that can negatively impact the physiochemical properties of conjugates. Cross-coupling with arylboronic acids and a new reagent, 3-((p-biphenyl-4-ylmethyl)thio)-6-methyltetrazine (b-Tz), proceeds under mild, PdCl2(dppf)-catalyzed conditions to introduce minimal, linker-free tetrazine functionality. Safety considerations guided our design of b-Tz which can be prepared on decagram scale without handling hydrazine and without forming volatile, high-nitrogen tetrazine byproducts. Replacing conventional Cu(I) salts used in Liebeskind-Srogl cross-coupling with a Ag2O mediator resulted in higher yields across a broad library of aryl and heteroaryl boronic acids and provides improved access to a fluorogenic tetrazine-BODIPY conjugate. A covalent probe for MAGL incorporating 6-methyltetrazinyl functionality was synthesized in high yield and labeled endogenous MAGL in live cells. This new Ag-mediated cross-coupling method using b-Tz is anticipated to find additional applications for directly introducing the tetrazine subunit to complex substrates.

We previously identified a pyridomorphinan (6, SRI-22138) possessing a 4-chlorophenyl substituent at the 5′-position on the pyridine and a 3-phenylpropoxy at the 14-position of the morphinan as a mixed mu opioid receptor (MOR) agonist and delta/kappa opioid receptor (DOR/KOR) antagonist with potent antinociceptive activity and diminished tolerance and dependence in rodents. Structural variations at the 5′- and 14-positions of this molecule gave insights into the structure-activity relationships for binding and functional activity. Subtle structural changes exerted significant influence, particularly on the ability of the compounds to function as agonists at the MOR. In vivo evaluation identified compound 20 (SRI-39067) as a MOR agonist/DOR antagonist that produced systemically active potent antinociceptive activity in tail-flick assay in mice, with diminished tolerance, dependence/withdrawal, reward liability, and respiratory depression versus morphine. These results support the hypothesis that mixed MOR agonist/DOR antagonist ligands may emerge as novel opioid analgesics with reduced side effects.
