design and synthesis of β-N-acetylhexosaminidase inhibitors along with their applicability to human disease treatment through biological evaluation in both an enzymatic and cellular setting. We investigated the importance of individual stereocenters, variations in structure–activityrelationships along with factors influencing cell penetration. To achieve these goals we modified nitrogen heterocycles

A straightforward and stereoselectivesynthesis of 3,4‐dihydroxyprolines and 3,4‐dihydroxyprolinols is described. The key reaction in this synthesis is a protective group‐controlled diastereoselective cyanation of a chiral acyliminium intermediate derived from l‐tartaric acid. Methanolysis of the obtained cyanolactam gave methyl 3,4‐dihydroxypyroglutamate that was converted to 3,4‐dihydroxyproline
