Axially chiral atropisomeric compounds are widely applied in asymmetric catalysis and medicinal chemistry, and efficient methods for their synthesis are in high demand. This applies in particular to atropisomers derived from five-membered aromatic rings because their lower barrier for rotation among the biaryl axis limits their asymmetric synthesis. We report here an enantioselective C-H functionalization method using our chiral RhJasCp complex for the synthesis of the biaryl atropisomer types that can be accessed from three different five-membered-ring heterocycles.

A number of N-(5-p-tolyl-1,3,4-thiadiazole-2-yl) benzamide derivatives were synthesized from aromatic acid. The antibacterial activity of these newly synthesized N-(5-p-tolyl-1,3,4-thiadiazole-2-yl) benzamide derivatives against Gram-positive bacteria and Gram-negative bacteria was also studied using the minimum inhibition concentration method. The synthesized compounds were showed better results for antibacterial evaluation against gram-positive (Staphylococcus aureus, Bacillus subtilis), gram-negative (Escherichia coli, Pseudomonas aeruginosa) and fungal strains (Candida albicans, A. niger) and were found to be good antibacterial and antifungal agents. Most of the derivatives showed significant antibacterial and antifungal activity against standard. Compared to other methods, the advantageous features of this methodology are operational simplicity, including excellent yields and short reaction time. The developed synthetic protocol represents a very simple and easy to handle for the synthesis of substituted N-(5-p-tolyl-1,3,4-thiadiazole-2-yl) benzamide derivatives.

Co-crystallizations can be utilized for generating new solid forms of a target substance in order to alter or enhance some specific bulk physical property. Generally, selection of the co-former (the necessary partner for the target molecule) is based on existing structural information about molecular recognition events involving complementary functional groups, and extensive experimental screening methods. In this study, we utilize structure-informatics in an attempt to predict if two different molecules will form a co-crystal or not. Our study is based on hydrogen-bond propensity (HBP), and the key premise of our approach rests on whether target-co-former interactions are more likely to take place than either target-target or co-formerco-former hydrogen bonds. We examined six different target molecules in combination with 25 possible co-formers each and used the HBP protocol for predicting if a co-crystal would form or not. The predictions were then compared with results from an experimental co-crystal screen of the 150 different combinations. The correct outcome was successfully predicted 92-95% of the time which shows that for this series of small molecules, HBP is a very reliable indicator for determining if a co-crystal will form between a target molecule and a particular co-former.

A concise and divergent approach for the total syntheses of four cembrane diterpenoids, namely (+)-sarcophytin, (+)-chatancin, (-)-3-oxochatancin, and (-)-pavidolideB, has been developed, and it also led to the structural revision of (-)-isosarcophytin. The key steps of the strategy feature a double Mukaiyama Michael addition/elimination, a Helquist annulation, two substrate-controlled facial-selective hydrations, and a pinacol rearrangement. The described syntheses not only achieved these natural products in an efficient manner, but also provided insight into the biosynthetic relationship between the two different skeletons.

The antifungal activity of a library of twenty-four aromatic methoximes was examined against five representative postharvest phytopathogenic fungi. The panel included Penicillium digitatum, Penicillium italicum, Rhizopus stolonifer, Botrytis cinerea and Monilinia fructicola, all of which cause relevant economic losses worldwide as a result of affecting harvested fruits. The minimum inhibitory concentrations and minimum fungicidal concentrations of each compound were defined and the main structure-activity relationships were determined. Although other congeners were more potent, drug likeliness considerations pointed to the methoxime derived from 2,4-dihydroxypropiophenone as the compound with the most suitable profile. The morphology of the colonies of the fungal strains treated with the methoxime was examined microscopically and the compound was also tested in freshly harvested peaches and oranges, exhibiting promising control profiles in both fruits, similar to those of the commercial agents Imazalil and Carbendazim.

Aqueous complexation of uranyl(VI) ions with methoxy- and methylbenzoates in 0.1 M NaClO4 solutions was studied by means of UV-vis absorption and Raman spectroscopy. The predominance of 1:1 complexation (uranyl to ligand) was verified for all uranyl carboxylates under acidic conditions (-log [H+] < 3.2), and absorption spectra, stability constants, and symmetric stretching frequencies of the uranyl group of the complexes were determined for the first time. For meta- and parasubstituted benzoates, a linear free energy relationship (LFER) was observed between the equilibrium constants for the protonation (log beta(p)) and uranyl complexation (log beta(U)) reactions, and the electronic effects of the substituents were successfully described by the Hammett equation. In the case of ortho-substituted benzoates, the stability constant of uranyl 2-methoxybenzoate is slightly lower than the LFER trend, which is generally explained by the destabilization of cross-conjugation in the uranyl complex due to the steric hindrance between the reaction center and adjacent methoxy group. On the contrary, the stability constant of uranyl 2-methylbenzoate is comparable to the LFER trend, implying that the steric effect is relatively insignificant for the smaller methyl group. The utility of such thermodynamic correlations between the uranyl-substituted benzoates is useful for the molecular understanding and predictive modeling of chemical interactions between actinyl(VI) ions and various organic carboxyl groups.

A green, efficient and cheap demethylation reaction of aromatic methyl ethers with mineral acid (HCl or H2SO4) as a catalyst in high temperature pressurized water provided the corresponding aromatic alcohols (phenols, catechols, pyrogallols) in high yield. 4-Propylguaiacol was chosen as a model, given the various applications of the 4-propylcatechol reaction product. This demethylation reaction could be easily scaled and biorenewable 4-propylguaiacol from wood and clove oil could also be applied as a feedstock. Greenness of the developed method versus state-of-the-art demethylation reactions was assessed by performing a quantitative and qualitative Green Metrics analysis. Versatility of the method was shown on a variety of aromatic methyl ethers containing (biorenewable) substrates, yielding up to 99% of the corresponding aromatic alcohols, in most cases just requiring simple extraction as work-up.

The depolymerization of the biopolymer lignin can give pure aromatic monomers but selective catalytic approaches remain scarce. Here, an approach was rerouted to deliver an unusual phenolic monomer. This monomer’s instability proved challenging, but a degradation study identified strategies to overcome this. Heterocycles and a useful synthetic intermediate were prepared. The range of aromatics available from the beta-O-4 unit in lignin was extended.
