Abstract A new series of ferrocene-containing thiazolylpyrazoles – 3-ferrocenyl-2-pyrazolyl-1,3-thiazolidin-4-ones have been synthesized using convenient one-pot three component condensation. Twelve newly synthesized compounds were fully characterized by spectroscopic (IR and NMR) and electrochemical methods (cyclic voltammetry). Single crystal X-ray structure analysis were undertaken on two compounds

A method for the ferrocene modification of amino acids of natural and synthetic origin has been developed. In the in vivo studies, the hippocampal electrical activity under the action of ferrocenyl(phenylpyrazolyl)glycine (1) was assessed. A meaningful rise (up to 25% compared to the control) in the response amplitudes of the focal potentials of the hippocampal region СА1 after intraperitoneal administration of compound 1 at the dose of 2.0 mg kg–1 was established

A series of ferrocene‐modified aminoacid methyl esters with pyrazole linker was prepared in good to quantitative yields starting from easy accessible ferrocene pyrazole carbaldehyde and aminoacids in racemic and enantio enriched forms under reductive amination conditions (NaBH (OAc)3, reflux, 3 hr). The resulting enantiomers were resolved using analytical HPLC on modified cellulose or amylose as

Porphyrin-modified ferrocenes were synthesized via the reductive amination reaction of ferrocenylpyrazolecarboxaldehydes and tetraphenylporphyrinamine. The steric hindrance of ferrocene moiety was found to play the key role in this reaction.

1-Aryl-3-ferrocenyl-4-formylpyrazoles were obtained from appropriate acetylferrocene arylhydrazones by the Vilsmeier—Haack reaction. Direct reductive amination of the resulting aldehydes with primary and secondary amines and amino acid esters in the presence of NaBH(OAc)3 was studied.
