methodology employing a Ni(II) 4,6-dimethylpyrimidine-2-thiolate cluster catalyst under different reaction conditions. This catalyst could tolerate a wide range of substrates and exhibited a high activity for the annulation reaction of secondary alcohols with 2-aminobenzyl alcohols to yield quinolines. This work is an example of precise chemoselectivity control by careful choice of reaction conditions.
New ferrocene containing 3-(arylthio)propan-1-ones: Synthesis, spectral characterization and crystal structure of 3-[(4-chlorophenyl)thio]-1-ferrocenylpropan-1-one, 3-[(4-chlorophenyl)thio]-1-ferrocenyl-3-phenylpropan-1-one and 3-[(4-chlorophenyl)thio]-3-ferrocenyl-1-phenylpropan-1-one

It was found that all three molecules do not form classical H-bonds and π⋯π interactions (regardless of the presence of 3 or 4 aromatic rings per a molecule). However, all three crystal structures abound in intermolecular C–H⋯π interactions while 2h and 3h in addition form intramolecular C–H⋯π as only evident interaction within the molecules.
Chiral aldehyde catalysis is uniquely suitable for the direct asymmetric α-functionalization of N-unprotected amino acids, because aldehydes can reversibly form imines. However, there have been few successful reports of these transformations. In fact, only chiral aldehyde catalyzed aldol reactions of amino acids and alkylation of 2-amino malonates have been reported with good chiral induction. Here
Two series of ferrocenyl chalcones were synthesized and evaluated for in vitro antiamoebic activity against HM1:IMSS strain of Entamoeba histolytica. The results showed that compounds of series B having ferrocene ring adjacent to carbonyl linkage were generally more active than compounds of series A. Compounds having unsubstituted phenyl ring, methoxy substitution, thiomethyl group, chloro group and nitro group, exhibited better antiamoebic activity than the reference drug metronidazole. The toxicological studies of these compounds on human kidney epithelial cell line showed that all compounds were non-toxic. The compound 1-ferrocenyl-3-(4-nitrophenyl)-2-propen-1-one (18) was found most active and least toxic among all compounds.

novel pyrimidine‐based ferrocenyl substituted organometallic compounds were synthesized via multistep reactions, well characterized by different spectroscopic techniques and elemental analyses and evaluated for in vitro antiprotozoal susceptibility against HM1: IMSS strain of Entamoeba histolytica. The results of antiprotozoal susceptibility unveiled these compounds, as new leads in protozoal chemotherapy
