Neoraufuracin and ambofuracin. Two novel 2-benzyl-2-O-(methyl-β-D-glucopyranos-2-yl)-trans-2,3-dihydrobenzofurans. Synthesis of the methylated aglycone
Abstract
The structures of two novel 2-benzyl-3-O-(methyl-β-D-glucopyranos-2-yl)-trans-2,3-dihydrobenzofurans are elucidated using high resolution 1H n.m.r., 13C n.m.r., and field-desorption mass spectrometry, and also by synthesis of a derivative of the aglycone moiety common to both compounds.
