There is provided a novel, useful dehydroxyfluorination agent containing sulfuryl fluoride (SO2F2) and an organic base that is free from a free hydroxyl group in the molecule. According to the present dehydroxyfluorination agent, it is not necessary to use perfluoroalkanesulfonyl fluoride, which is not preferable in large-scale use, and it is possible to advantageously produce optically-active fluoro derivatives, which are important intermediates of medicines, agricultural chemicals and optical materials, for example, 4-fluoroproline derivatives, 2′-deoxy-2′-fluorouridine derivatives, optically-active α-fluorocarboxylate derivatives, and monofluoromethyl derivatives, even in large scale.
提供了一种新颖、有用的去羟基氟化剂,它含有亚磺酰氟(SO2F2)和有机碱,该有机碱分子中没有自由羟基。根据这种去羟基氟化剂,不需要使用不适合大规模使用的全氟烷基磺酰氟,而且即使在大规模生产中也可以优势地生产出光学活性的氟衍生物,这些氟衍生物是药物、农业化学品和光学材料的重要中间体,例如4-氟脯氨酸衍生物、2'-去氧-2'-氟尿苷衍生物、光学活性的α-氟羧酸酯衍生物和单氟甲基衍生物。
