Abstract
The 1H n.m.r. spectrum of β-D-arabinose was measured at 89.6 MHz in the presence of boron(III) oxide. The boron(III) oxide produces remarkable chemical shift changes in hydroxy proton signals and the signals of all methine and methylene groups in the β-D-arabinose dissolved in (CD3)2SO. The assignments of the spectrum of β-D-arabinose with 2 mol. equiv. of boron(III) oxide were determined by spin-decoupling experiments.Keywords
