Commonly, hydrolase-catalysed reactions are used for kinetic resolutions of alcohols, amines and acids. Only a few applications in total syntheses have been described. Most of these examples are for the synthesis of amides and peptides. Here, the synthesis of all
Both enantiomers of several phenylethylamines, structurally related to amphetamine, have been prepared in good yields and excellent enantiomeric purity by enzymatic kinetic resolution using CAL-B and ethyl methoxyacetate as the acyl donor. In the case of the 4-hydroxyderivative of amphetamine
Chinese hamsters were exposed to acetone, methyl ethyl ketone, ethyl acetate and 2-methoxy ethyl acetate, known to be strong inducers of aneuploidy in the yeast Saccharomyces cerevisiae. All solvents yielded negative results in the micronucleus test, whereas the vinca alkaloid
Rapid communications in mass spectrometry : RCM, 15(15), 1327-1333 (2001-07-24)
Sample preparation methods and data acquisition protocols were optimized for the application of matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOFMS) to high-throughput quantitative analysis of low molecular mass substrates and products of an enzyme-catalyzed reaction. Using a deuterlum-labeled internal standard
The enantiomers of aromatic 4-dibenzocyclooctynol (DIBO), used for radiolabeling and subsequent conjugation of biomolecules to form radioligands for positron emission tomography (PET), were separated by kinetic resolution using lipase A from Candida antarctica (CAL-A). In optimized conditions, (R)-DIBO [(R)-1, ee
