## Abstract The NMR parameters of (β)βscopolamine free base in CDCl~3~ determined by Sarazin __et al.__ were used to reevaluate some of the stereochemical conclusions recently reported by the authors. Similarly to the case with the protonated salt, the major contributor to the fast exchange limit t

Isocyclosporins are isomers of cyclosporins deriving from an N,O-acyl transfer occurring under acidic conditions. For the identification by 1 H NMR of isocyclosporins prepared in organic solvents the signal at 2.3 ppm assigned to three hydrogens of the NHCH 3 group is considered. Results reported he
13C and 'H NMR parameters were measured for isoproterenol in solution. Spin-lattice relaxation rates were considered and C-H and H-H J couplings were determined. The t rotamer was shown to occur in a much greater abundance than the two g rotamers. Dynamics in solution were interpreted in terms of a
## Abstract The conformational analysis of three 1,2β3,4βdiβ__O__βMethylenepyranoses was carried out using NMR (coupling constants and homonuclear Overhauser effect) and theoretical (MM2 calculations) methods. A preferred twistβboat conformation was found.
Two conformations of the cis-cyclohexano-8-crown-3 molecule were detected at 185 K. From relative 13 C NMR peak area measurements, the conformation with the O-CH 2 -O unit equatorial was found to be favoured by 4.4 Ε‘ 0.4 kJ mol 1 . In the spectrum of the minor conformer at low temperature, a 9.6 ppm
The 6-Mono-and trans-6,7-di-substituted derivatives of 5,6,7,8-tetrahydrodibenzo[a,c]cyclo-octene exist in solution in two different conformations. The experimental DG o values obtained from 1 H NMR spectra are compared with the DE steric and DG values calculated by molecular mechanics and semiempir
