Process for the manufacture of a compound of formula R1OOC-CH(OCH2F)-COOR2 (I) or R3HNOC-CH(OCH2F)-CONHR4 (II) wherein R1, R2, R3, R4 are equal or different from each other and are independently selected from H; an alkyl group having from 1 to 10 carbon atoms which is optionally substituted by at least one halogen atom; an aralkyl group; or an aryl group, comprising reacting a compound of formula R1OOC-CH(OCH2X)-COOR2 (III) or R3HNOC-CH(OCH2X)-CONHR4 (IV) wherein X is a leaving group that can be substituted by nucleophilic substitution, and wherein R1, R2, R3, R4 have the same meaning as above, with at least one source of nucleophilic fluorine.
制备化合物R1OOC-CH(OCH2F)-COOR2(I)或R3HNOC-CH(OCH2F)-CONHR4(II)的过程,其中R1,R2,R3,R4相等或不同,且独立地选自H;具有1至10个碳原子的烷基,其可以被至少一个卤素原子取代;芳基烷基;或芳基,包括将式R1OOC-CH(OCH2X)-COOR2(III)或R3HNOC-CH(OCH2X)-CONHR4(IV)的化合物与至少一种含有亲核氟的源反应,其中X是可以被亲核取代的离去基团,R1,R2,R3,R4具有上述相同的含义。
