โœฆ Synopsis

Empirical force-field calculations and ir and 'H-nmr spectra indicate that five-membered (C5) and seven-membered (C;q) hydrogen-bonded rings are the preferred conformations of acetyl-L-Phe p-acetyl and p-valeryl anilides in nonpolar media. The Cs/Cp ratio was found to be dependent on the dryness of the solute and the solvent. This fact and the results from conformational-energy calculations suggest that a molecule of water participates in the stabilization of the Cqq conformation.

Conformational studies of acetylated open chain hexitol derivatives, possessing similar structures but differing in their configuration have been made by analysing their NMR spectra. It is shown, that the carbon chain of all three (manno-, ido-and gluco-) isomers is present in a non planar non zigza
