✦ Synopsis

Abstract

NMR spectra of a series of N‐arylsuccinanilic acids, N‐arylsuccinimides, N‐arylmaleanilic acids, and N‐arylmaleimides were examined to estimate the electronic effect of the amide and imide groups on the chemical shifts of the hydrogen and carbon nuclei of the benzene ring.

Rotational barriers about the CÈN bonds of several N-acyl-N-methyl-a-amino acids and their esters R3COÈ N(R4)ÈCR1R2ÈCOOR5, and also N-Boc-protected dipeptides, were determined and the steric e †ects caused by the substituents R1-R5 are discussed by comparing them with the results of MM3 calculations
