Studies of the perturbing effect of the trifluoromethylanthryl carbinol used as chiral solvating agent (CSA) upon the 1H NMR spectra of chiral α-O-substituted β-hydroxylamides demonstrated the ability of this fluoroalcohol to afford diastereomeric

In order to evaluate the deterioration of paper, methods such as pH measurement, viscosity or mechanical properties have found a large application. However, these relatively simple methods have their disadvantages, such as a rather large sample size,

Solutions in N,N-dimethylacetamide (DMAC)-LiCl were prepared from two different pulps (sulphite pulp from softwood and cotton linters) in different ageing states. Degradation of the stirred solutions at 35-40 degrees C was observed by determining the

Two series of isoxazoles substituted by long alkyl or alkenyl chains in the α position with respect to the oxygen atom or in the α position with respect to the two heteroatoms have been synthesized. Starting from 3,5-dimethylisoxazole, the regiosel

Several syntheses of special isoxazoles bearing a long alkyl or alkenyl side chain in the α position of the nitrogen are presented. A very convenient route in the case of an alkyl side chain is the classical 1,3-dipolar cycloaddition of a nitrile-ox

A cyclodepsipeptide-glutathionyl conjugate has been analysed for the first time using negative-ion fast-atom bombardment linked-scan mass spectroscopy. Fragment anions produced by collision-induced dissociation are discussed.
