Negative ion chemical ionization (NICI) using a chiral reagent gas such as (2S,3S) butanediol (GSS) allows the differentiation of chiral alpha hydroxy esters (MR or MS). The distinction is significantly enhanced by using CID on the deprotonated hetero dimer [M + (GSS-H)]-. The contribution of a non covalent [M + (G SS-H)]- competitive form is very minor. In fact, a covalent form appears favored. To produce a covalent adduct ion, an enantioselectivity of the alkoxide attack on the electrophilic ester site to form a tetravalent adduct is suggested by the product ion abundances. This observed steric control is consistent with the one observed in solution (Cram-Felkin addition/reduction orientation). The dissociations under collision conditions of the product deprotonated diastereomeric compounds show a stereospecific effect in the elimination of alcohol from the tetravalent adduct ions rather than a regeneration of the deprotonated diol reagent as expected from non-covalent heterodimer. This study shows an orientation with a chiral compound that allows, from an analytical point of view, the distinction of enantiomers and the attribution of chirality in the gas phase under NICI conditions.

A simple procedure was suggested for the chromatographic analyses of bio-oils from pyrolysis of various feedstock employing different technologies. An acetonitrile solution of each bio-oil was prepared without any extraction or other sample pretreatments. Preliminary thin layer chromatography showed a large number of compounds having a broad range of retention factors (Rfs) among 0-1. Products having a retention factor over 0.9 were mainly detected by GC while some other compounds were only identified by HPLC. GC/MS-FID analysis was used to identify and quantify compounds using peak areas and relative response factors (RRFs). A new equation was proposed to estimate RRFs of compounds identified via their MS spectra when experimental RRFs were not readily available. The novel procedure was employed to characterize bio-oils from pyrolysis of wood of different source or obtained using different pyrolysis procedure. Using this RRF method guaiacol, furfural, butan-2-one, levoglucosan, acetic acid and many other compounds were quantified in bio-oil samples. Different amount of them were found as a function of the type of wood, and pyrolysis conditions adopted. For instance levoglucosan was the main compound using carbon as MW absorber however acetic acid was prevalent when a MW absorber was not employed and both of them were absent in bio-oils from classical heating. The HPLC/MS of bio-oils showed cyclohexancarboxylic acid, 1,2,4-trimethoxybenzene and 2,6-dimethylphenol among the main products present in all bio-oils. On the contrary 4-hydroxyacetophenone and (3,4,5-trimethoxy) acetophenone were present in bio-oil from pyrolysis of wood using MW oven and 2,5-furandiylmethanol when a MW oven without any absorber was employed. Cyclohexanone was present in bio-oils obtained with a thermal heating or a MW oven without any absorber.

The enzymes of the non-mevalonate pathway for isoprenoid biosynthesis are potential new targets for the development of selective drugs for the treatment of important infectious diseases. This pathway is used by major human pathogens, such as Plasmodium falciparum and Mycobacterium tuberculosis, but not by humans. The fourth enzyme in the pathway is the kinase IspE, and we report here the development and biological evaluation of new ligands for this enzyme from Escherichia coli and Aquifex aeolicus species as model systems for the pathogenic enzymes. The study focuses on analysis of the methylerythritol pocket of the 4-diphosphocytidyl-2-C-methyl-D-erythritol binding site. A series of 5-substituted 1-(thiolan-2-yl)cytosines with increasingly polar substituents were synthesized, opting for possible water-replacements in that sub-pocket as well as a high water-solubility of the ligands. In vitro studies showed IC 50 values in the micromolar range against E. coli IspE, but, unexpectedly, no inhibition against A. aeolicus IspE within the measurement range of the biological tests.
