Synthesis and structure of biologically active ferrocenylalkyl polyfluoro benzimidazoles
摘要:
The title compounds were synthesized in quantitative yields by interacting cl-hydroxyalkyl ferrocenes with polyfluoroalkyl benzimidazoles in an aqueous-organic medium in the presence of HBF4. The resulting diastereomers and enantiomers were resolved using HPLC on silica bonded chiral stationary phases based on chiral cyclodextrins and cyclic antibiotics. The X-ray determination of molecular and crystal structure of 1-ferrocenylmethyl-2-(trifluoromethoxyfluoromethyl)benzimidazole (1) was carried out. (C) 1999 Elsevier Science S.A. All rights reserved.
