Conformational analysis of acylated 1,1-bis(acylamido)-1-deoxypentitols by fourier-transform, p.m.r. spectroscopy
The conformations of eight acylated 1,1-bis(acylamido)-1-deoxypentitols in solution have been studied by pulse, Fourier-transform, p.m.r. spectroscopy at 90 Mhz. The arabino and lyxo derivatives adopt the zigzag conformation, whereas the ribo and xylo derivatives favor different sickle conformations...

The conformations of eight acylated 1,1-bis(acylamido)-1-deoxypentitols in solution have been studied by pulse, Fourier-transform, p.m.r. spectroscopy at 90 Mhz. The arabino and lyxo derivatives adopt the zigzag conformation, whereas the ribo and xylo derivatives favor different sickle conformations. The validity of the conformational assignments of these derivatives by the p.m.r. method is discussed. The relative merits and accuracy of the continuous-wave and pulse-Fourier p.m.r. spectroscopic methods in the conformational analysis of carbohydrates are appraised, and the applicability of the exponential-filtering technique to enhancement of either the sensitivity or the resolution of their spectra is demonstrated. © 1974. |
