depolymerization reactions.
Epimerization can be
spontaneous (generally a slow process), or
catalysed by enzymes, e.g. the
epimerization between the
sugars N-acetylglucosamine...

presence of an
acidic center between two
carbonyl groups allows for easy
epimerization at the

- (S,R) is soluble. The
precipitation of the (R,R)
product drives the
epimerization equilibrium reaction to form this as the
major product.

Although epimerization was
historically an
issue in the
synthesis of 2,5-DKPs,
several mild
methods have been
developed recently that
avoid epimerization. 2...

Since the

epimerize out any of the
undesired erythro isomers. The drug that
