Epimerization of C-1 alkynyl group on pyranose ring through dicobalt hexacarbonyl complexes
摘要:
Alkynyl group attached on the C-1 position of pyranose ring was epimerized through dicobalt hexacarbonyl complex with trifluoromethane sulfonic acid. Three steps involving complexation, acidic transformation and decomplexation afforded overall epimerization.
