    Abstract: The present disclosure provides compounds useful for enzymatic glycan remodeling of a glycoprotein. Also provided is a method for remodeling a glycoprotein using M6P-glycan oxazolines in a one-pot deglycosylation/transglycosylation process, which may enable siteselective M6P-glycan remodeling of glycoproteins to obtain homogeneous products. The remodeled glycoprotein (such as a recombinant human acid α-glucosidase) may have enhanced affinity for the CI-MPR, increased uptake by a cell, and improved therapeutic efficacy compared to the original glycoprotein. A method of treating Pompe disease using a glycanremodeled lysosomal enzyme is also provided.

    Abstract: This invention is based on the discovery that homogeneous catalysts, [Rh(C 2 H 4 ) 2 Cl] 2 and/or [Rh(COD) 2 ][BF 4 ], can be used to produce spinetoram in higher yields at lower catalyst loadings as compared to previous methodologies. In addition, one or more phosphorus ligand donors can also be added to further increase yields/efficiency. The methods and/or systems provided herein enable cost-effective ways to produce spinetoram in large quantity with relatively simple procedures.
