  描述：

  Ethyl 5-chloro-4,4-difluoropentanoate 在 磷酰基乙酸 、 20 % Pd(OH)2/C 、 水 、 氢气 、 sodium hydride 、 溶剂黄146 、 1-丙基磷酸酐 、 三乙胺 、 N,N-二异丙基乙胺 、 lithium hydroxide 作用下， 以 四氢呋喃 、 乙醇 、 乙酸乙酯 、 N,N-二甲基甲酰胺 、 叔丁醇 为溶剂， 50.0 ℃ 、517.12 kPa 条件下， 生成 1((3S,4S)-4-amino-1-(4-(3,3-difluoropyrrolidin-1-yl)-1,3,5-triazin-2-yl)pyrrolidin-3-yl)-5,5-difluoropiperidin-2-one

  名称：

  1-((3S,4S)-4-Amino-1-(4-substituted-1,3,5-triazin-2-yl) pyrrolidin-3-yl)-5,5-difluoropiperidin-2-one inhibitors of DPP-4 for the treatment of type 2 diabetes

  摘要：

  A 3-amino-4-substituted pyrrolidine series of dipeptidyl peptidase IV (DPP-4) inhibitors was rapidly developed into a candidate series by identification of a polar valerolactam replacement for the lipophilic 2,4,5-trifluorophenyl pharmacophore. The addition of a gem-difluoro substituent to the lactam improved overall DPP-4 inhibition and an efficient asymmetric route to 3,4-diaminopyrrolidines was developed. Advanced profiling of a subset of analogs identified 5o with an acceptable human DPP-4 inhibition profile based on a rat PK/PD model and a projected human dose that was suitable for clinical development.
