  Bronsted acids of anionic chiral Co(III) complexes were found to act as efficient phase-transfer catalysts for the diastereoselective iodoglycosylation or iodocarboxylation of glycals with a variety of alcohols or carboxylic acids, respectively, with N-iodosuccinimide as the iodo cation source. The corresponding 2-deoxy-2-iodoglycosides, including monosaccharides and disaccharides, and 2-deoxy-2-iodoglycosyl

• Glycosylations of Glycals using <i>N</i>-Iodosuccinimide (NIS) and Phosphorus Compounds for Syntheses of 2-Iodo- and 2-Deoxyglycosides

  The glycosylations of glycals and alcohols using N-iodosuccinimide (NIS) and a catalytic amount of PPh3 effectively proceeded under mild conditions to provide the corresponding 2-deoxy-2-iodoglycosides in high yields. The reactivity of the iodoglycosylations with PPh3 significantly increased in comparison to that using NIS alone as an activator. In addition, the glycosylations of glycals and alcohols using catalytic amounts of NIS and P(OPh)(3) were effectively realized to give the corresponding 2-deoxyglycosides in high yields.
