Chiral trimethylsilylated C2-symmetrical diamines as phosphorous derivatizing agents for the determination of the enantiomeric excess of chiral alcohols by 1H NMR
The use of organophosphorus derivatising agents, prepared from C2 symmetric trimethylsilylated diamines, for the 1H NMR and 31P NMR determination of the enantiomeric composition of chiral alcohols is described.
متن کاملDetermination of concentration and enantiomeric excess of amines and amino alcohols with a chiral nickel(II) complex.
A chiral N,N'-dioxide-Ni(II) complex was found to exhibit highly enantioselective fluorescent recognition of chiral amines and amino alcohols. It can be used to determine their concentration and ee value. Using a 96-well plate, high-throughput screening for enantiomer discrimination was accomplished.
متن کاملDetermination of the enantiomeric purity of mevalonolactone via NMR using a chiral lanthanide shift reagent.
Simple methods for determining the enantiomeric purity of mevalonolactone and linalool by NMR using the chiral shift reagent Eu(hfc)3 are reported. These methods are more reliable than polarimetry and require only a few milligrams of sample to detect as little as 2% of the minor enantiomer. The accuracy of these methods is limited primarily by spectral resolution for samples of high enantiomeri...
متن کاملNovel chiral derivatizing isothiocyanate-based agent for the enantiomeric excess determination of amines.
The expedient synthesis of a novel chiral (1S,2S)-N-[(2-isothiocyanato)cyclohexyl] trifluoromethanesulfonamide and its use as a derivatizing auxiliary for the straightforward determination of optical purity of chiral amines are reported.
متن کاملSensing of enantiomeric excess in chiral carboxylic acids.
Cinchona alkaloids (quinine, quinidine, cinchonine, cinchonidine) alkylated at N(1) with chloromethyl anthracene can serve as fluorescent sensors for chiral carboxylic acids. These cinchona ammonium salts are shown to bind chiral carboxylic acids while displaying an increase in fluorescence intensity that can be utilized in determination of enantiomeric excess (ee). Sensor arrays composed of fo...
