일반 설명
(S)-(-)-α-Methoxy-α-(trifluoromethyl)phenylacetic acid is commonly used as a derivatizing agent in Mosher ester analysis and Mosher amide analysis, which are NMR-based methods for determining the absolute configuration of the chiral carbon center in secondary alcohols and amines, respectively.[1]

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

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
