Enantiomerically pure tetrahydro-5-oxo-2-furancarboxylic esters from dialkyl 2-oxoglutarates

Enantiomerically pure tetrahydro-5-oxo-2-furancarboxylic esters can be prepared either by enzymatic resolution of the racemic gamma-lactones themselves or by bioreduction with baker’s yeast of dialkyl 2-oxoglutarates and subsequent cyclization of the resulting dialkyl 2-hydroxyglutarates. The best results were obtained by the former route, by which the desired compounds were isolated in high enantiomeric excess. Bioreductions were less satisfactory. In fact the hydroxyester intermediates were initially formed as racemic mixtures and their final enantiomeric enrichment was reached by asymmetric destruction, occurring in the bioreaction medium, however at the same time large amounts of alkyl 4-hydroxybutanoates were formed as side products.

A novel approach to assess the quality and authenticity of Scotch Whisky based on gas chromatography coupled to high resolution mass spectrometry

Whisky is one of the most popular spirit drinks in the world. Unfortunately, this highly valued commodity is vulnerable to fraud. To detect fraudulent practices and document quality parameters, a number of laboratory tests based on various principles including chromatography and spectroscopy have been developed. In most cases, the analytical methods are based on targeted screening strategies. Non-targeted screening (metabolomics fingerprinting) of (semi)volatile substances was used in our study. Following the pre-concentration of these compounds, either by solid phase microextraction (SPME) or by ethyl acetate extraction, gas chromatography (GC) coupled to tandem mass spectrometry (Q-TOF mass analyser) was employed. Unsupervised principal component analysis (PCA) and supervised partial least squares discriminant analysis (PLS?DA) were used for evaluation of data obtained by analysis of a unique set of 171 authentic whisky samples provided by the Scotch Whisky Research Institute. Very good separation of malt whiskies according to the type of cask in which they were matured (bourbon versus bourbon and wine) was achieved, and significant ¡ämarkers? for bourbon and wine cask maturation, such as N-(3-methylbutyl) acetamide and 5-oxooxolane-2-carboxylic acid, were identified. Subsequently, the unique sample set was used to construct a statistical model for distinguishing malt and blended whiskies. In the final phase, 20 fake samples were analysed and the data processed in the same way. Some differences could be observed in the (semi)volatile profiles of authentic and fake samples. Employing the statistical model developed by PLS-DA for this purpose, marker compounds that positively distinguish fake samples were identified.

Design and synthesis of potential inhibitors of the ergosterol biosynthesis as antifungal agents

A series of azolylmethyloxolane derivatives with modified sterol side-chain structures, designed as potential dual functional inhibitors of cytochrome P450 14alpha-demethylase (14DM) and Delta24-sterol methyltransferase (24-SMT) based on the common characteristic features of 24-aminosterols and azole antifungal agents, were synthesized and evaluated for their antifungal activities and inhibitory activities of 14DM and 24-SMT. Among these compounds, imidazolylmethyloxolane derivatives 28a and 28b showed potent in vitro antifungal activities comparable to those of itraconazole. However, the in vitro bioactivities have not been linearly translated into in vivo protection data for some unknown reasons. Copyright (C) 2000 Elsevier Science Ltd.

Stereoselective synthesis of the specialized pro-resolving and anti-inflammatory mediator resolvin E1

The n-3 polyunsaturated fatty acids eicosapentaenoic acid, docosahexaenoic acid and n-3 docosapentaenoic acid, act as substrates for the biosynthesis of specialized pro-resolving lipid mediators. Resolvin E1, produced from eicosapentaenoic acid, was the first specialized pro-resolving lipid mediator reported. This oxygenated polyunsaturated fatty acid displays a plethora of interesting biological activities, and has entered initial clinical trial development programs. The Evans-Nagao aldol reaction, a stereoselective alkyne reduction and a Z-selective Wittig reaction, were utilized for the stereocontrolled synthesis of resolvin E1 presented herein. In addition, results from HPLC analysis revealed that the synthetic material matched authentic resolvin E1.

Influence of harvest maturity and fruit logistics on pineapple (Ananas comosus [L.] Merr.) volatiles assessed by headspace solid phase microextraction and gas chromatography-mass spectrometry (HS-SPME-GC/MS)

Profiling of volatiles from pineapple fruits was performed at four ripening stages using headspace solid-phase microextraction and gas chromatography-mass spectrometry (HS-SPME-GC/MS). In total, 142 volatiles were detected, of which 132 were identified. Multivariate data analysis was carried out to assess the effect of post-harvest storage on volatiles composition of green-ripe sea-freighted pineapple in comparison to air-freighted fruits harvested at full maturity. The latter fruits were characterised by volatiles described as potent odorants in pineapples, such as delta-octalactone, gamma-lactones, 1-(E,Z)-3,5-undecatriene and 1,3,5,8-undecatetraene, as well as various methyl esters. In contrast, post-harvest storage of green-ripe sea-freighted fruits resulted in an increased formation of ethyl esters, acetates, acetoxy esters and alcohols, thus allowing the authentication of sea- and air-freighted pineapples, respectively. Particularly, compounds presumably derived from methyl-branched amino acid catabolism were identified in the fruits at later post-harvest stages. In addition, physicochemical traits were determined to characterise the fruit maturity stages.
