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.
本发明提供了一种新型、有用的脱羟基氟化剂,它含有硫酰氟(SO2F2)和有机碱,分子中不含有游离羟基。根据本发明的脱羟基氟化剂,不需要使用在大规模使用中不可取的全氟烷基磺酰氟,而且可以有利地生产光学活性氟衍生物,这些衍生物是药物、农药和光学材料的重要中间体,例如,4-氟脯氨酸衍生物、2'-脱氧-2'-氟尿苷衍生物、光学活性α-氟羧酸盐衍生物和单氟甲基衍生物,甚至可以大规模生产。
