Analysis of the absolute configuration of chiral [16O, 17O, 18O]sulphate monoesters by Fourier transform infrared spectroscopy
Abstract
The symmetric and antisymmetric SO2 stretching region of the i.r. spectrum provides a means of distinguishing between (1R)-3-hydroxy-1-methylpropyl [(S)-16O,17O,18O]sulphate and [(R)-16O,17O,18O]sulphate after cyclisation to an isotopomeric mixture of (4R)-4-methyl-2,2-dioxo-1,3,2-dioxanthianes.
