Crystal structure of methyl 1,2,3,4-tetra-O-acetyl-beta-D-glucopyranuronate.
The identity of the crystalline product formed by the acetylation of a mixture of methyl alpha- and beta-D-glucopyranuronates has been confirmed as being methyl 1,2,3,4-tetra-O-acetyl-beta-D-glucopyranuronate (3), which agrees with the assignment from 1H NMR. The absolute configuration of compound 3 was assigned to agree with the known chirality of the precursor sugar, D-glucono-6,3-lactone.
