A variable-temperature13C cross-polarization magic angle spinning NMR study of some unusual dynamic and phase properties of (±)-3,4-di-O-acetyl-1,2,5,6-tetra-O-benzyl-myo-inositol, ‘jumping crystals’

Variable-temperature 13C CP/MAS NMR experiments were carried out on crystalline (±)-3,4-di-O-acetyl-1,2,5,6-tetra-O-benzyl-myo-inositol. Three distinct phases can be distinguished from their NMR characteristics, each stable over a well defined tempe

Observation of discrete thiazolidine ring conformations in frozen aqueous solutions of penicillins by13C CP–MAS NMR spectroscopy

Autor: Jamila Fattah, J. Mark Twyman, Christopher M. Dobson

Publikováno v: J. Chem. Soc., Chem. Commun.. :647-649

Resonances from two distinct thiazolidine ring conformers have been resolved in the 13C CP-MAS spectra of frozen aqueous solutions of penicillins; the relative intensities of the resonances correlate well with previous estimates of the populations of
