Conformational analysis of (R,S)-4-amido-2,4-dimethyl-butyric acid derivatives
摘要:
NMR spectra of various N-acyl derivatives of (R,S)-4-amino-2,4-dimethyl-butyric acid show these compounds to be biconformational, populating the conformers 4 and 5 of the molecular backbone. Both predominant conformers have the amide group gauche to the main chain, (C) 1999 Elsevier Science Ltd. All rights reserved.
