New RNA modifications are needed to advance our toolbox for targeted manipulation of RNA. In particular, the development of high-performance reporter groups facilitating spectroscopic analysis of RNA structure and dynamics, and of RNA-ligand interactions has attracted considerable interest. To this end, fluorine labeling in conjunction with F-19-NMR spectroscopy has emerged as a powerful strategy. Appropriate probes for RNA previously focused on single fluorine atoms attached to the 5-position of pyrimidine nucleobases or at the ribose 2 ‘-position. To increase NMR sensitivity, trifluoromethyl labeling approaches have been developed, with the ribose 2 ‘-SCF3 modification being the most prominent one. A major drawback of the 2 ‘-SCF3 group, however, is its strong impact on RNA base pairing stability. Interestingly, RNA containing the structurally related 2 ‘-OCF3 modification has not yet been reported. Therefore, we set out to overcome the synthetic challenges toward 2 ‘-OCF3 labeled RNA and to investigate the impact of this modification. We present the syntheses of 2 ‘-OCF3 adenosine and cytidine phosphoramidites and their incorporation into oligoribonucleotides by solid-phase synthesis. Importantly, it turns out that the 2 ‘-OCF3 group has only a slight destabilizing effect when located in double helical regions which is consistent with the preferential C3 ‘-endo conformation of the 2 ‘-OCF3 ribose as reflected in the (3)J (H1 ‘-H2 ‘) coupling constants. Furthermore, we demonstrate the exceptionally high sensitivity of the new label in F-19-NMR analysis of RNA structure equilibria and of RNA-small molecule interactions. The study is complemented by a crystal structure at 0.9 angstrom resolution of a 27 nt hairpin RNA containing a single 2 ‘-OCF3 group that well integrates into the minor groove. The new label carries high potential to outcompete currently applied fluorine labels for nucleic acid NMR spectroscopy because of its significantly advanced performance.

We synthesized N-benzoyl-protected peptide nucleic acid (PNA) monomers, which are robust under the conditions for deprotecting the 9-fluorenylmethoxycarbonyl (Fmoc) group by piperidine but are removable by aqueous ammonia and hence totally compatible with Fmoc-solid phase synthesis. This new invention expands the range of available nucleobase sequences, allowing us to use acid-sensitive PNA oligomers and purine nucleotides (both of which are difficult to use in the conventional methods) in the preparation of PNA-DNA chimeras to avoid the drawbacks of traditional PNAs.

Friedel-Crafts (FC) acylation reactions were exploited in the preparation of ketone-functionalized aromatics. Environmentally more friendly, solvent-free mechanochemical reaction conditions of this industrially important reaction were developed. Reaction parameters such as FC catalyst, time, ratio of reagents and milling support were studied to establish the optimal reaction conditions. The scope of the reaction was explored by employment of different aromatic hydrocarbons in conjunction with anhydrides and acylation reagents. It was shown that certain FC-reactive aromatics could be effectively functionalized by FC acylations carried out under ball-milling conditions without the presence of a solvent. The reaction mechanism was studied by in situ Raman and ex situ IR spectroscopy.

A variety of appropriately substituted internal alkynes were transformed into the corresponding cyano-substituted phenanthrenes, dihydronaphthalenes, and cyclohepta-1,3,5-trienes in moderate to excellent yields by treatment with imidazolium thiocyanate 1, which serves as an easy to handle [CN](+) precursor, in the presence of BCl3. The synthetic value of the method is additionally demonstrated by the transformation of the primarily obtained products into heavily substituted quinolines. Additionally, the dynamic properties of the prepared dibenzocyclohepta-1,3,5-trienes have been investigated.

Semivolatile organic compounds (SVOCs) emitted from open biomass burning (BB) can contribute to chemical and physical properties of atmospheric aerosols and also may cause adverse health effects. The polar fraction of SVOCs is a prominent part of BB organic aerosols, and thus it is important to characterize the chemical composition and reactivity of this fraction. In this study, globally and regionally important representative fuels (Alaskan peat, Moscow peat, Pskov peat, eucalyptus, Malaysian peat, and Malaysian agricultural peat) were burned under controlled conditions using the combustion chamber facility at the Desert Research Institute (DRI). Gas- and particle-phase biomass-burning emissions were aged in an oxidation flow reactor (OFR) to mimic 5-7 d of atmospheric aging. Fresh and OFR-aged biomass-burning aerosols were collected on Teflonimpregnated glass fiber filters (TIGF) in tandem with XAD resin media for organic carbon speciation. The polar fraction extracted with dichloromethane and acetone was analyzed with gas chromatography mass spectrometry (GC-MS) for 84 polar organic compounds – including mono- and dicarboxylic acids, methoxylated phenols, aromatic acids, anhydrosugars, resin acids, and sterols. For all these compounds, fuel-based emission factors (EFs) were calculated for fresh and OFR-aged samples. The carbon mass of the quantified polar compounds was found to constitute 5 % to 7 % of the total organic compound mass. A high abundance of methoxyphenols (239 mg kg(-1) for Pskov peat; 22.6 % of total GC-MS characterized mass) and resin acids (118 mg kg(-1) for Alaskan peat; 14.5 % of total GC-MS characterized mass) was found in peat-burning emissions (smoldering combustion). The concentration of some organic compounds (e.g., tetracosanoic acid) with a molecular weight (MW) above 350 g mol(-1) decreased after OFR aging, while abundances of low-MW compounds (e.g., hexanoic acid) increased. This indicated a significant extent of fragmentation reactions in the OFR. Methoxyphenols decreased after OFR aging, while a significant increase (3.7 to 8.6 times) in the abundance of dicarboxylic acids emission factors (EFs), especially maleic acid (10 to 60 times), was observed. EFs for fresh and ratios from fresh-to-aged BB samples reported in this study can be used to perform source apportionment and predict processes occurring during atmospheric transport.

A transition-metal-free electrophilic bromination and iodination of arene through C-H cleavage at room temperature has been developed in excellent to quantitative yields with broad arene scope and good regioselectivity, in which environment-benign and readily available sodium halides, NaBr or NaI, were employed as halogen sources in accompany with N-fluorobenzenesulfonimide (NFSI) as an oxidant. Studies have also demonstrated that, in this air- and moisture-resistant scalable halogenation under mild conditions, the oxidant NFSI is reduced to dibenzenesulfonimide which usually serves as the starting material for the preparation of NFSI, rendering this facile and versatile protocol promising potentials for future applications in organic synthesis.

Basicity is an important parameter with impact on biological systems and technological problems. The HOMO-LUMO and FERMO theoretical approaches can describe the acid-base behavior of compounds as amines, carboxylic acids and alcohols. In this work, a method was developed using the localization degree Gamma(FERMO) parameter based on projection operators to quantify the localization of molecular orbitals. This new method was employed for the analysis of the protonation reaction of 30 organic compounds. The quantitative data from our findings were able to reproduce experimental data, pointing out that the FERMO approach could better describe the acid-base behavior of the investigated compounds.

To obtain a pure product without the isomer byproducts is a goal that many chemists are pursuing. As one kind of very important synthesis method, the photochemical reaction is simple and straightforward yet low-selective. In this work, a coordination interaction based oriented synthesis strategy has been proposed to realize the precise stereochemical control of the isomeric cyclic compounds in the photocycloaddition reaction. Through fixing the reactants via coordination interactions, the arrangements and configurations of the reactants can be adjusted, thereby successfully producing all of the related photocycloaddition products without isomer byproducts for the first time. This work not only provides a new route to synthesize the pure cyclic compounds but also expands the application of the photocycloaddition reaction.
