Synthesis and enantiomeric resolution of ferrocenyl(alkyl)azoles
摘要:
Ferrocenyl(alkyl)azoles were synthesized in high yields by interaction of alpha-ferrocenylcarbinoles with azoles in aqueous-organic in the presence of HBF4 or by interaction of alpha-ferrocenylcarbinoles with N,N'-carbonyldiimidazole, N,N'-thionyldiimidazole, N,N'-thionyldibenzimidazole in boiling dichloromethane. The resulting enantiomers of ferrocenyl(alkyl)azoles and some carbinoles were separated using HPLC on silica bonded chiral stationary phases based on cyclodextrins and modified cellulose.
