Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Hydrofluoric Acid | HCID 14917 | — |
| Reactant | (2R,3S,4S,5R)-2,3,4,5,6-pentahydroxyhexanal | HCID 3037556 | — |
| Product | alpha-D-galactosyl fluoride | HCID 10921145 | 98.9% |
Reaction Steps
In an apparatus and by the procedure according to Example 1, 1 g of D-galactose was reacted with 10 g of hydrogen fluoride, the mixture was left to stand for 1 hour at -30° to -40° C. and the hydrogen fluoride was then stripped out within 15 minutes by blowing in nitrogen. The working-up gave α-D-galactosyl fluoride (about 1 g) which was identified by elemental analysis, thin-layer chromatogram and 19F and 13C nuclear magnetic resonance spectra (cf. J. E. C. Barnett et al., Biochem. J. 105 (1967), page 669). Melting point: 130° (decomposition).
