  描述：

  4--(3R)-piperidinyloxy>benzaldehyde 在 盐酸 、 哌啶鎓苯甲酸盐 作用下， 以 溶剂黄146 、 甲苯 为溶剂， 反应 3.5h， 生成 (5E)-5-[[4-[(3R)-1-[(5-hydroxy-2,2,4,6,7-pentamethyl-3H-1-benzofuran-3-yl)methyl]piperidin-3-yl]oxyphenyl]methylidene]-1,3-thiazolidine-2,4-dione

  摘要：

  Several thiazolidinedione derivatives having 5-hydroxy-2,3-dihydro-2,2,4,6,7-pentamethylbenzofuran moieties and their 5-benzyloxy derivatives and 5-hydroxy-2,4,6,7-tetramethylbenzofuran moieties were synthesized and evaluated in db/db mice. Insertion of an N-Me group into the linker between thiazolidinedione and substituted benzofuran pharmacophores showed considerable improvement in their euglycemic activity. Further improvement has been observed when a pyrrolidine moiety is introduced in the structure to give 5-[4-[N-[3(R/S)-5-benzyloxy-2,3-dihydro-2,2,4,6,7-pentamethylbenzofuran-3-ylmethyl]-(2S)-pyrrolidin-2-ylmethoxy]phenylene]-thiazolidine-2,4-dione (21a). At a 100 mg/kg/day dose of the maleate salt, compound 21a reduced the plasma glucose and triglyceride to the level of lean littermate, i.e. 8 +/- 1 mM, and is the most potent and efficacious compound reported in this series.
