| titleOfInvention | Production of sugar ketal |
| abstract | PURPOSE: To obtain industrially and advantageously a sugar ketal useful for protecting OH and a synthetic intermediate, by reacting a sugar with a ketone in the presence of antimony pentachloride or pentafluoride. n CONSTITUTION: A sugar, e.g. D-arabinose, is reacted with a ketone, e.g. acetone, in a molar amount of 2W10 times of the theoretical amount, in the presence of preferably 0.05W5wt%, based on the sugar, antimony pentachloride or antimony pentafluoride preferably at 20W100°C for 1W8hr. In the process, an inert solvent or the above-mentioned ketone is used as a solvent. The reaction solvent is then distilled away to afford the aimed sugar ketal, e.g. 1,2:3,4-di-O-isopropylidene-β-D-arabinopyranose. n COPYRIGHT: (C)1985,JPO&Japio |
