This method consists in the derivatization of an alcohol possessig unknown absolute configuration with one or both enantiomers of an auxiliary reagent. The resulting diastereoisomer spectra are registered and compared, and the chemical shift differences (DdR,S = dR - dS) are measured. The determination of the absolute configuration of the alcohol molecule is based on the correlation between its chiral center and the auxiliary reagent's chiral center. Therefore, the determination of the absolute configuration depends on aromatic ring shielding effects on the substituents of the alcohol as evidenced by the 1H NMR spectrum.Submitted by JURANDI DE SOUZA SILVA (jssufba@hotmail.com) on 2011-11-28T13:46:38Z No. of bitstreams: 1 26838.pdf: 442089 bytes, checksum: f4912842c48a98bc5d6f4499ff30cf9f (MD5)Made available in DSpace on 2011-11-28T13:46:38Z (GMT).
