Methoxy-group migration in the hydrolysis of the 4-nitrobenzene-p-sulphonates of methyl β-D-xylopyranoside and methyl β-D-glucopyranoside
Abstract
One of the products of hydrolysis of methyl 4-O-nitrobenzene-p-sulphonyl-β-D-xylopyranoside, at pH 5, is 4-O-methyl-L-arabinose, while the corresponding β-D-glucopyranoside yields both 4-O-methyl-D-galactose and methyl α-L-altrofuranoside as products.
