Syntheses of new N-demethyl-N-substituted analogues (propyl, allyl) of 1-fluorocodeine and their 7,8-dihydro derivatives were described starting from codeine. 1-Fluoronorcodeine and 1-fluorodihydronorcodeine were prepared by N-demethylation with α-chloroethyl chloroformate from the corresponding 6-O-acetyl protected derivatives. 3-O-Demethylation of 1-fluorocodeine and 1-fluorodihydrocodeine with boron
从可待因开始描述了1-氟可待因的新的N-去甲基-N-取代的类似物(丙基,烯丙基)及其7,8-二氢衍生物的合成。通过用α-氯乙基氯甲酸酯从相应的6- O-乙酰基保护的衍生物进行N-脱甲基化来制备1-氟代可待因和1-氟二氢诺可待因。3- Ô 1-fluorocodeine和1- fluorodihydrocodeine用三溴化硼的-Demethylation分别导致1-fluoromorphine和1- fluorodihydromorphine。将1-氟二氢吗啡乙酰化为3,6-二-O-乙酰基-1-氟二氢吗啡。8-氟可待因和N由适当的1-氟可待因衍生物通过酸催化的重排合成了丙基-丙基-8-氟阿朴可待因。
