This work deals with the synthesis and evaluation of new compounds designed by combination of 1,4-naphthoquinone and ferrocene fragments in a 3-ferrocenylmethyl-2-hydroxy-1,4-naphthoquinone arrangement. A practical coupling reaction between 2-hydroxy-1,4-naphthoquinone and ferrocenemethanol derivatives has been developed. This procedure can be carried out "on-water", at moderate temperatures and without auxiliaries or catalysts, with moderate to high yields. The synthesized derivatives have shown significant in vitro antiplasmodial activity against chloroquine-sensitive and resistant Plasmodium falciparum strains and it has been shown that this activity is not related to the inhibition of biomineralization of ferriprotoporphyrin IX. Binding energy calculations and docking of these compounds to cytochrome b in comparison with atovaquone have been performed.
Efficient regio- and diastereo-controlled synthesis of 1,1′- and 1,1′,2,2′-functionalised ferrocenes and the formation of 2-oxa[3]ferrocenophanes

The synthesis of a C2 symmetric 1,1′ ,2,2′-tetrasubstituted ferrocene system was discussed. The route involved the reduction of ferrocenyl carbonyl compounds which gave access to a range of alcohols, alkenes, alkanes, ethers, and 2-oxa[3]ferrocenophanes depending on the precise conditions used. The loss of optical activity of 1,1′-bis(hydroxymethyl)ferrocenes and 1,1′-bis(hydroxymethyl)ruthenocenes, which had been prepared by asymmetric reduction, was demonstrated in an acidic medium by extensive 1H NMR studies.
