The anomeric hydroxyl group of various pyranose hemiacetals can be esterified with inversion of configuration, conveniently, mildly and on large-scale using triphenylphosphine (TPP), with either diisopropylazodicarboxylate (DIAD) or diethylazodicarboxylate (DEAD) and a carboxylic acid in THF at either −50° C or at room temperature.
