Sc. Ennis et al., Stereoselective synthesis of alpha-glucosides and beta-mannosides: Tethering and activation with N-iodosuccinimide, SYNLETT, (9), 1999, pp. 1387-1390
The stereoselective synthesis of both alpha-glucosides and beta-mannosides
may be readily achieved by the use of N-iodosuccinimde, both to effect mixe
d ketal formation and subsequent intramolecular aglycon delivery (IAD).
