| Authors: | Wies&#x;awa Kudelska |
| Abstract: | An ambident O,O‐dialkylphosphoroselenothioate is glycosidated in the presence of boron trifluoride etherate to give both Se‐ and S‐glycosyl‐phosphoroselenothioates, the former predominating. The stereochemical course of this reaction depends on the kind of sugar substrates. By selective oxidation of the mixture of products, the Se‐glycosyl derivative is isolated. © 1999 John Wiley & Sons, Inc. Heteroatom Chem 10: 259–262, 1999 |
