A convenient and scalable synthesis of DGJNAc ID from D-glucuronolactone in an overall yield of 20% is provided. DGJNAc is the first highly potent and specific competitive inhibitor of GalNAcases. DGJNAc ID is also a competitive inhibitor of -hexosaminidases. Synthesis and activity of L-DGJNAc IL is also shown. The use of DGJNAc as a potent and specific inhibitor of GalNAcases will allow useful investigation and treatment of a number of diseases, including Schindler Disease.
