Efficient synthesis of L-galactose from D-galactose

Racemic protein crystallography is an emerging methodology to obtain high-resolution protein structures. Preparation of both a mirror image of protein and a mirror image of glycan is essential to apply the new methodology to glycoprotein. This article describes an efficient synthesis of L-galactose that is amirror image of D-galactose. The developed method takes only 6 steps from D-galactose without any chromatographic purification.
