| titleOfInvention | Process for production of optically active alpha-fluorocarboxylate ester |
| abstract | An optically active alpha-fluorocarboxylate ester can be produced by reacting an optically active a-hydroxycarboxylate ester with sulfuryl fluoride (SO2F2), trifluoromethanesulfonyl fluoride (CF3SO2F)or nonafluorobutanesulfonyl fluoride (C4F9SO2F) in the presence of an organic base and in the absence of a reactive solvent. More preferably, the reaction solution produced after the reaction is comp leted is added with an acid and is subjected to distillation purification, thereby producing the optically active alpha-fluorocarboxylate ester with a higher purity. The process enables to produce an optically active alpha-fluorocarboxylate ester advantageously on a large scale. |
