Regioselective Acylation of Secondary Hydroxyl Groups by Means BOP‐Cl
摘要:
Methyl 2-O-acyl alpha-D-glucopyranosides are regioselectively formed with good yields by acylation of the correspondent 6-O-trityl pyranosides with carboxylic acids and (BOP-Cl). No acyl migration was observed in the deblocking of the primary hydroxyl group with p-toluensulfonic acid.
