| | 9-O-(1,2:5,6-Di-O-isopropylidene-alpha-D-glucofuranosyl)-9-boratabicyclo[3.3.1]nonane potassium salt Usage And Synthesis |
| Uses | 9-O-(1,2:5,6-Di-O-isopropylidene-alpha-D-glucofuranosyl)-9-boratabicyclo[3.3.1]nonane potassium salt is a chiral borohydride reagent for enantioselective reduction of ketones.
| | Synthesis | 9-BBN, by reaction with the chiral alcohol 1,2;5,6-di-O-isopropylidene- α-D-glucofuranose (DPGF) (both commercially available), is transformed into the borinic ester 9-O-DIPGF-9-BBN which, by treatment with a modest excess (1.1-1.5 equiv) of potassium hydride, is completely transformed within 2 h into K-glucoride (9-O-(1,2:5,6-Di-O-isopropylidene-alpha-D-glucofuranosyl)-9-boratabicyclo[3.3.1]nonane potassium salt).
| | Precautions |
K-glucoride (9-O-(1,2:5,6-Di-O-isopropylidene-alpha-D-glucofuranosyl)-9-boratabicyclo[3.3.1]nonane potassium salt) is relatively stable toward disproportionation at rt, especially when the THF solution is stored over excess potassium hydride under a positive pressure of nitrogen. It is usually prepared and stored in THF solution.
