MECHANISMS FOR THE REACTIONS OF THE ANOMERIC TETRA-<i>O</i>-ACETYL-<scp>D</scp>-GLUCOPYRANOSYL BROMIDES WITH PYRIDINE AND 2-PYRIDONE
Reaction of tetra-O-acetyl-α-D-glucopyranosyl bromide (I) with pyridine at high dilution gives a high yield of N-(tetra-O-acetyl-β-D-glucopyranosyl)-pyridinium bromide (II). The addition of tetra-n-butylammonium bromide diverts the reaction to the formation of the highly strained α-anomer (III) of I...
