Cesium carbonate-promoted synthesis of aryl methyl sulfides using: S -methylisothiourea sulfate under transition-metal-free conditions

In the presence of cesium carbonate, an efficient synthesis of aryl methyl sulfides by the reactions of aryl halides with commercially available S-methylisothiourea sulfate is developed. This odourless and highly crystalline solid can be used as the substitute for malodorous methanethiol. The gram-scale reaction also proceeds smoothly without the use of column chromatography separation. Similarly, 2-(dimethylamino)ethylthio and cyclopropylmethylthio groups can be easily introduced into the aromatic rings from the corresponding S-[2-(dimethylamino)ethyl]isothiourea dihydrochloride and S-cyclopropylmethylisothiourea hydrobromide. The possible reaction mechanism is proposed. It is believed that this route to aryl alkyl sulfides is well competitive with currently known methods due to its wide substrate scope, excellent yields, easy operation and transition-metal-free conditions.

Discrimination between defective and non-defective Brazilian coffee beans by their volatile profile

The coffee roasted in Brazil is considered to be of low quality, due to the presence of defective coffee beans that depreciate the beverage quality. In view of the fact that coffee flavour is directly related to the volatile compounds produced during roasting, the objective of the present study was to perform a comparative evaluation of the volatile fraction of defective (black, immature, sour) and healthy coffee beans, in order to find possible chemical markers for detection of defective coffee beans in roasted coffee. Volatiles extraction and concentration was performed by solid phase micro-extraction (SPME) of the roasted coffee headspace, using a triple phase (divinylbenzene/carboxen/polydimethylsiloxane) fiber. Analysis of the volatile profiles was performed by GC-MS. The results obtained showed that the proposed methodology was adequate for extraction, concentration and analysis of the coffees volatile profile. Several substances were identified as possible markers for differentiating black, sour and immature beans from healthy coffee beans. Statistical analysis of the data by principal components (PCA) demonstrated that the volatile profile enables the differentiation of healthy and defective coffees. The data were separated into two major groups, one represented by immature and black beans and the other by healthy and sour coffee beans. Such results indicated that black and sour beans can be associated to fermentation of immature and of healthy beans, respectively.

The mechanism of peptide bonds cleavage and volatile compounds generated from pentapeptide to heptapeptide via Maillard reaction

This study is focused on the mechanism of peptide bond cleavage and volatile Maillard reaction products (MRPs) following reaction of 10 artificial oligopeptides with cysteine, xylose and thiamine. LC-TOF/MS was used to detect the chemistry of peptide bond cleavage in liquid media. GC-O-MS and a carbohydrate module labelling (CAMOLA) method were used to analyse and identify the formation pathways of volatile and semi-volatile MRPs. In this study, the theoretical foundation of seven principles of influencing factors acting on peptide chain cleavage has initially been summarised. At the start of this study assumptions were also made relating to heat resistance of peptide chain positions. A universal formation pathway map and a model of possible mechanisms of common product formation were proposed. This model was authenticated by this scientific study.

Using peptidic inhibitors to systematically probe the S1? site of caspase-3 and caspase-7

(Chemical Equation Presented) Fifteen ketone-containing peptides were designed, synthesized, and used to probe the effect of substitution at the P1? position on caspase-3 and -7 inhibition. Even with the large bias of Ac-Asp-Glu-Val-Asp at the P4-P1 positions, certain peptides with cyclic functionality in the P1? position show a dramatically reduced ability to inhibit these caspases. Additionally, trends toward isozyme selectivity were also uncovered for particular P1? substituents. The data indicate that substitution in the P1? position can drastically affect both caspase inhibition and selectivity.

136. Triple-Helix Formation by Pyrimidine Oligonucleotides Containing Nonnatural Nucleosides with Extended Aromatic Nucleobases: Intercalation from the Major Groove as a Method for Recognizing C·G and T·a Base Pairs

The sequence-specific recognition of double-helical DNA by oligonucleotide-directed triple helix formation is limited primarily to purine tracts. To identify potential lead compounds which are able to extend the sequence repertoire of triple helical complexes, we designed two carbocyclic nucleosides with nucleobases attached via amide bonds. N 5-[(1R,2S,3R,4R)-3-hydroxy-4-(hydroxymethyl)-2-methoxycyclopentyl]-2- {[1H-pyrrol-2-yl)carbonyl]-amino}thiazole-5-carboxamide (L1) and 2-benzamido-N 5-[(1R,2S,3R,4R)-3-hydroxy-4-(hydroxymethyl)-2-methoxycyclopentyl] thiazole-5-carboxamide (L2) were synthesized and incorporated into pyrimidine oligonucleotides. The 2-(trimethylsilyl)ethoxymethyl (SEM) protecting group for the 1H-pyrrole NH was found to be compatible with DNA solid-phase synthesis of pyrimidine oligonucleotides. By quantitative DNase I footprinting analysis, both nonnatural nucleosides L1 and L2 showed preferential binding of pyrimidine over purine bases: L1/2 · (C-G) ? L1/2 · (T · A) > L1/2?(G · C) ? L1/2 · (A · T). Comparison with the previously reported nonnatural nucleosides with extended aromatic nucleobases 1-(2-deoxy-beta-D-ribofuranosyl)-4-(3-benzamidophenyl)-imidazole (D3) and N4-[6-(benzamido)pyridin-2-y1]-2?-deoxycytidine (bzM) suggests that the observed binding selectivity C · G ? T · A > G · C ?A · T for the nucleoside analogs L1, L2, D3, and bzM is derived from sequencespecific intercalation with preferential stacking of their nucleobases over pyrimidine · purine Watson-Crick base pairs.

Thiazolium-based catalysts for the etherification of benzylic alcohols under solvent-free conditions

Thiazolium and imidazolium hybrid materials were prepared by radical reactions between a mercaptopropyl-modified SBA-15 mesoporous silica and bis-vinylthiazolium or bis-vinylimidazolium dibromide salts. These hybrid materials were characterized by several techniques and were employed in the etherification reaction of 1-phenylethanol. Solvent-free conditions at 160C under different gas phases (oxygen, air, nitrogen and argon) were used. The thiazolium-based material displayed excellent performances. Further studies were carried out using unsupported thiazolium salts, with or without a methyl group at the C-2 position of the thiazolium moiety. These studies allowed us to propose a reaction mechanism. The supported thiazolium-based material was successfully used in the etherification reaction of two other benzylic alcohols and also in seven consecutive cycles. This work represents the first use of thiazolium-based compounds as catalysts for the etherification reaction of alcohols.
