A method to determine the absolute configuration of 2,3-epoxy-2-methylbutanoate ester residues in natural products is presented, based on (i) the reduction of the ester function to yield a 2-methyl-1,2-butanediol, (ii) esterification of the obtained primary alcohol with either (R)-(+)- or

Cyclodextrin (CD) derivatives are important selectors for analytical chiral recognition. Their enantioselectivities and chemical properties depend on ring size and on nature, number and location of substituents. This paper describes the synthesis of 6-O-TBDMS-2,3-O-methyl beta-cyclodextrins bearing in position 2 either

Two different mixture synthesis routes have been used to make the four stereoisomers of petrocortyne A. A first quick and dirty route provided a mixture of the four isomers in nonselective fashion. Mosher and 2-naphthylmethoxyacetic acid (NMA) ester methods were

Methods for the nuclear magnetic resonance and gas chromatographic analysis of the enantiomers of p-trifluoromethylmandelic acid (p-TFM) and Mosher's acid (alpha-methoxy-alpha-(trifluoromethyl)phenylacetic acid) present in rat urine samples are described. Gas chromartography was performed using cyclodextrin capillary columns with both compounds
