¹H NMR Study of 2‐Deoxy‐D‐Arabino‐Hexopyranose (2‐Deoxy Glucopyranose), 2‐Deoxy‐D‐Lyxo‐Hexopyranose (2‐Deoxy Galactopyranose) and 2′‐Deoxy Lactose. Shift Increment Studies in 2‐Deoxy Carbohydrates

Abstract

Abstract Complete analyses of the 1 H n.m.r. spectra at 300 MHz of D 2 0 solutions of 2‐deoxy‐D‐arabino‐hexopyranose, 2‐deoxy‐D‐lyxo‐hexopyranose and 2′‐deoxy lactose. Chemical shifts in the deoxy monosaccharides and in 2′‐deoxy lactose are compared with those previously obtained in the parent aldohexopyranoses, glucobioses and D‐galactopyranosyl‐D‐glucoses. Increment values are suggested in order to predict chemical shifts in 2‐deoxy derivatives from the well known rules for aldohexopyranoses.
