Synthesis and NMR experiments of (4,5,6-13C)-deoxymannojirimycin. A new entry to 13C-labeled glycosidase inhibitors

The synthesis of (4,5,6-13C)-deoxymannojirimycin is described. The route employed is based on Sharpless asymmetric epoxidation of (1,2,3-13C)(E)-2,4-pentadien-1-ol and uses ring-closing metathesis as a key step. The labeled compound may be easily used for protein-binding experiments using NMR spectroscopic methods.
