A new approach to functionalize porphyrinoids was developed based on the Vilsmeier formylation followed by the azine formation and a new class of the compounds namely azines of porphyrinoids was obtained. Variously substituted azine porphyrins, chlorins and their dyads were synthesized, and their structural and electronic parameters were studied with X-ray diffraction analysis, electronic absorption and emission spectra, electrochemistry and DFT calculations. Azine represents a very peculiar bridge with an unclear conjugation ability affecting optical properties of chromophores. This work was aimed to reveal azine properties and the influence of the azine bridge on the chromophores linked. The results of investigation allowed to conclude that azine bridge can partly be regarded as a conjugation switch with a high threshold level of switching, where limited conjugation in the ground state can be greatly increased at higher energy states of the azine molecule.

The possibility of using maghemite (gamma-iron(III) oxide) as a catalyst for the oxidation of alcohols with atmospheric oxygen has been explored. It has been shown that maghemite is active in the oxidation of benzyl alcohols. In the case of benzyl alcohol, the oxidation leads to benzaldehyde with nearly 100% selectivity. It has been found that the addition of small amounts of basic cocatalysts can substantially increase the yield of the target products.

UV/Vis absorption and NMR spectroscopy titrations have been used to investigate the formation of complexes between cations and neutral H-bond acceptors in organic solvents. Complexes formed by two different H-bond acceptors with fifteen different cations were studied in acetone and in acetonitrile. The effects of water and ion pairing with the counter-anion were found to be negligible in the two polar solvents employed for this study. The data were used to determine self-consistent H-bond donor parameters (a) for a series of organic and inorganic cations; guanidinium, primary, tertiary and quaternary ammonium, imidazolium, methylpyridinium, lithium, sodium, potassium, rubidium and caesium. The results demonstrate the transferability of a parameters for cations between different solvents and different H-bond acceptor partners, allowing reliable prediction of cation recognition properties in different environments. Lithium and protonated nitrogen cations form the most stable complexes, but the a parameter is only 5.0, which is similar to the neutral H-bond donor 3-trifluoromethyl, 4-nitrophenol (a 1/4 5.1). Quaternary ammonium is the weakest H-bond donor investigated with an a value of 2.7, which is comparable to an alcohol. The a parameters for alkali metal cations decrease down the group from 5.0 (Li+) to 3.5 (Cs+).

A series of hybrid antimicrobial compounds were prepared by carboxylic acid protection of 6-aminopenicillanic acid using benzyl alcohol and thionyl chloride succeeded by azide displacement using trifluoromethanesulfonyl azide in dichloromethane. The azide thus formed was reacted with substituted alkynes to furnish benzyl-protected penicillin-triazole conjugates. Benzyl deprotection of the conjugates resulted in furnishing PNTCs under water methanol mixture using Pd/C as a catalyst. The PNTCs (7a-j) formed were screened for in vitro antibacterial potency against pathogenic strains of Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, and Streptococcus pyogenes and antifungal potency against Candida albicans, Aspergillus niger, and Aspergillus clavatus. Further antimicrobial evaluation revealed compounds 7c, 7d, 7e, 7g, and 7i to be the most compounds of the series with minimum inhibitory concentration value for antibacterial in the range 0.5-50 mu g/mL and for antifungal in the range 9-300 mu g/mL. Toxicological analysis documented for compounds 7c, 7d, 7e, 7g, and 7i revealed compound 7i to be the most promising member of the series with 1000 and 500 mg/kg LD50, and no-observed-adverse-effect level to facilitate future clinical studies of the same.

Gray mold caused by Botrytis cinerea is a fungal disease that can determine significant economic losses of apple during the storage phase. An alternative to reduce the use of traditional synthetic fungicides is to employ the yeast Starmerella bacillaris as biological control agent (BCA), also with positive effect on apple juice fermentation for the production of cider. Thus, we aimed to evaluate the safety of 16 S. bacillaris strains and their ability to control B. cinerea. In addition, the fermentation performances in apple juice and the volatile organic compounds (VOCs) profile were assessed, both in single-strain and in sequential fermentations with Saccharomyces cerevisiae. The in vitro assays showed that all S. bacillaris strains can be considered safe from the analyzed virulence factors, and were able to significantly constrain the growth of B. cinerea, reducing mycelial growth of 50% in dualculture and of 90% through VOCs. Moreover, in vivo antagonistic assays revealed a visible decrease of gray mold rot symptoms on apples confirming the potential of S. bacillaris as BCA. GC-MS analysis of the ciders obtained showed increased concentrations in the sequential fermentation of some higher alcohols and terpenes, positively correlated with the cider aromatic quality, and suggested the involvement of benzyl alcohol, known for its antimicrobial action, in the biocontrol efficacy.

OPAHs and SPAHs are highly genotoxic and would largely be formed during the thermal conversion of lignin. Herein, the distribution of OPAHs and SPAHs in lignin pyrolytic tar at different temperatures is elaborated with ESI (-) FT-ICR MS and GC-MS, and the formation routes of two typical OPAH and SPAH are deeply explored via DFT. It is found that most of oxygen-containing compounds convert to phenols and their homologues such as guaiacol (a typical precursor of OPAHs) with the temperature increased. The tar prepared at high temperature contains disulfide, thiophene and thiophene homologues, which are typical precursors of SPAHs. FT-ICR-MS strongly suggests that molecular mass of OPAHs and SPAHs compounds mainly concentrates between 200 Da and 400 Da with carbon atom number from 5 to 25 and DBE from 4 to 15. Higher temperature significantly promotes deoxygenation reaction since weighted average carbon atom number and DBE of molecules increase 28.4 % and 12.9 %, while the corresponding weighted average oxygen atom number decreases from 7.21 to 5.96 with temperature rising from 500 degrees C to 900 degrees C. Incorporating with DFT calculation, the pathways of OPAHs and SPAHs during lignin pyrolysis at high temperature are concluded: Guaiacol converts to 1-methoxynaphthalene via 4 methylation reactions, and butene firstly generates thiophene and then converts to methyl-benzothiophene. Among the reactions above, benzene ring and thiophene ring generation steps possess the highest energy barriers (436.74 kJ/mol and 446.33 kJ/mol), further illustrating higher temperature promotes the formation of OPAHs and SPAHs.

The wide range of geographical cocoa production areas and the increasing consumption trend towards single origin products induced the necessity to verify and certify cocoa beans origin for quality assurance purposes. In this study cocoa beans of various origins were examined by machine olfaction and machine vision techniques. Fifty-nine fermented and dried Forastero cocoa beans from 23 different geographical origins (Africa, Americas, Southeast Asia) were investigated using Proton Transfer Reaction-Quadrupole interface-Time of Flight-Mass Spectrometry and Hyperspectral Imaging to elucidate the geographical information in the beans. The volatile and spectral fingerprints showed the same tendency in clustering samples from Africa separate from those from the Americas. High variability was observed for the Southeast Asian samples, which is most likely related to differences in fermentation. Machine olfaction and machine vision characterization provided a similar degree of separation but are complementary rapid techniques, which may be further developed for use in practical settings.

We herein report the conventional and microscale parallel synthesis of selective inhibitors of human blood coagulation factor XIIa and thrombin exhibiting a 1,2,4-triazol-5-amine scaffold. Structural variations of this scaffold allowed identifying derivative 21i, a potent 29 nM inhibitor of FXIIa, with improved selectivity over other tested serine proteases and also finding compound 21m with 27 nM inhibitory activity toward thrombin. For the first time, acylated 1,2,4-triazol-5-amines were proved to have anticoagulant properties and the ability to affect thrombin- and cancer-cell-induced platelet aggregation. Performed mass spectrometric analysis and molecular modeling allowed us to discover previously unknown interactions between the synthesized inhibitors and the active site of FXIIa, which uncovered the mechanistic details of FXIIa inhibition. Synthesized compounds represent a promising starting point for the development of novel antithrombotic drugs or chemical tools for studying the role of FXIIa and thrombin in physiological and pathological processes.

In contrast to methyl phenylacetates, methyl arylacetates do not provide syn-aldols in the dicyclohexylboron triflate/triethylamine (Chx(2)BOTf/Et3N)-mediated enolboration-aldolization reaction. However, a combination of a less bulky boron reagent (dibutylboron triflate, n-Bu2BOTf), a bulky amine (i-Pr2NEt, and ambient temperature is required to obtain syn-aldols from methyl arylacetates. The corresponding anti-aldol products have been synthesized by the enolboration-aldolization of methyl arylacetates in the presence of Chx(2)BOTf/Et3N at a lower temperature. We report the first example of a complementary syn- and anti-selective enolboration-aldolization of arylacetates.

A cobalt-complex-catalyzed borylation of a wide range of alkyl halides with a diboron reagent (B(2)pin(2) or B(2 )neop(2)) has been developed under mild reaction conditions, demonstrating the first cobalt-mediated cross-coupling with alkyl electrophiles. This protocol allows alkyl boronic esters to be accessed from alkyl halides, including alkyl chlorides, which were used rarely as coupling partners. Mechanistic studies reveal the possible involvement of an alkyl radical intermediate in this cobalt-mediated catalytic cycle.
