CARB 80 |
| Alpha-GlcNAc mercaptan 1 reacts with certain phosphorus(III) and (V) reagents to afford glycomimetic S-glycosylphosphothioates such as 2. Under oxidative conditions, however, an intermediate S-glycosylphosphothioite 3 can give, instead of 2, a rearranged P-glycosylphosphonothioate (4). Preparative, mechanistic, and stereochemical aspects of this radical rearrangement will be presented. |
