bonyl-DL-3,3-difluorophenylalanine which have been successfully introduced into peptide syntheses. Several fluorinated peptides have been obtained either by active ester coupling methods, mixed anhydride synthesis or with the aid of dicyclohexylcarbodiimide (DCC) in presence of 1-hydroxybenzotriazole (HOBt). The method has been applied to the preparation of seven hitherto unpublished representative
已经开发了用于N -9-芴基甲氧基羰基-DL-2-氨基-3,3-二氟丁酸和N -9-芴基甲氧基羰基-DL-3,3-二氟苯丙氨酸的方便的合成方法,它们已经成功地引入了肽合成中。通过活性酯偶联方法,混合酸酐合成或在1-羟基苯并三唑(HOBt)存在下借助二环己基碳二亚胺(DCC)获得了几种氟化肽。该方法已用于生物学目的和结构化学研究中,迄今尚未制备的七个代表性的3-(1,1'-二氟烷基)-2,5-二氧杂哌嗪的制备。
