Both ferrocenethiol and ferrocene-1,1′-dithiol, Fe(C5H5)(C5H4SH) and Fe(C5H4SH)2, add to activated olefins to give 1:1 and 1:2 adducts, respectively.The base-catalysed (NEt3) reactions of the monofunctional ferrocenethiol with the mono-olefins methyl methacrylate, methyl vinyl sulfone and benzylidene acetone lead to expected 1:1 adducts whereas 2:1 adducts are obtained with bifunctional olefins such as divinyl sulfone and dibenzylidene acetone.The corresponding bifunctional ferrocene-1,1′-dithiol gives 1:2 adducts with methyl methacrylate, methyl vinyl ketone and benzylidene acetone.For comparison, the aliphatic 2-ferrocenyl-ethanethiol, Fe(C5H5)(C5H4-CH2CH2SH), was reacted with methyl vinyl sulfone and divinyl sulfone.In all cases, the disulfides Fc-SS-Fc and Fc-CH2CH2-SS-CH2CH2-Fc, respectively, are also formed.The acid-catalysed (HCl) reactions of ferrocenethiol and ferrocene-1,1′-dithiol, Fe(C5H5)(C5H4SH) and Fe(C5H4SH)2, with isobutyl vinyl ether produce the expected 1:1 and 1:2 adducts although the formation of dimercaptals is also possible.Thus the reaction of ferrocene-1,1′-dithiol with isobutyl vinyl ether leads to both the 1:2 adduct and the 2-methyl 1,3-dithia-<3>ferrocenophane, Fe(C5H4S)2CH(CH3), and the HCl-catalysed addition of ferrocenethiol to 1,4-butadienol divinyl ether gives 1,1-di(ferrocenylmercapto) ethane, CH3CH(SFc)2.The new sulfur derivatives of ferrocene were characterized by 1H and 13C NMR spectroscopy.Keywords: Iron; Ferrocene; Ferrocene thiol; Addition to olefins; NMR

The nonfluorinated parent dibenzalacetone 1 as well as the corresponding penta- (2) and decafluorinated (3) derivative compounds were prepared, crystallized, and subjected to co-crystallization experiments. Only 3 yielded a 1:1 co-crystal with 1, while 2 did not form co-crystals with either 1 or 3. Powder X-ray diffraction patterns were determined to verify the co-crystallization experiments. The influence of the fluorine on the molecular geometry and crystal packing were studied and comparatively discussed. Conclusions with reference to the priority of Ar…ArF contact modes in the crystalline packing being in competition with other fluorine and non-fluorine involved supramolecular interactions were drawn.

The phosphine-catalyzed annulations between Morita-Baylis-Hillman adduct carbonates and enones are reported. Under the catalysis of PBu3 (20 mol %), cascade [3 + 2] cyclization-allylic alkylation, [2 + 2 + 1] annulation, and [3 + 2] cyclization reactions chemoselectively occur depending on the substituent variation of both the carbonate and enone. These reactions provide efficient syntheses of highly functionalized cyclopentenes and cyclopentanes.

A new series, of gamma-amino butyric acid analogs were designed and synthesized as novel potent GABA-AT inhibitors. A structure-activity relationship study was performed by correlating the effect of different substituents with GABA-AT inhibitory activity of the title compounds. The preliminary bioassays showed that acid hydrazones exhibited excellent inhibitory activities in micromolar (0.07-0.56 muM) range, while Schiff’s bases showed variable results. The most potent compound, 4-amino-N’-[(1Z)-1-(2-bromophenyl) ethylidene]butanehydrazide (AHG177) showed inhibitory potency (IC50) of 0.073 muM. Aminobutyrate transaminase is a pyridoxal-P enzyme which follows a bi-bi ping pong mechanism and in pyridoxamine form can readily transaminate only with succinic semialdehyde and 2-oxoglutarate. The results strongly suggest that only the pyridoxal form of the enzyme is capable of reacting with the ligands. Our findings open up the possibility to extend this protocol to different databases in order to find new potential inhibitor for promising targets based on a rational drug design process.

Study of the reactivity of peroxides derivable from ketones by reaction with hydrogen peroxide has required reexamination of preparative methods.Conditions for obtaining five known peroxides from cyclohexanone and the new 1-(1-hydroxycyclohexyldioxy)-1-(1-hydroperoxycyclohexyldioxy)cyclohexane (10) are carefully defined.An improved general method for obtaining cyclic diperoxides (3,3,6,6-tetrasubstituted 1,2,4,5-tetraoxans) (6) has been developed and used to obtain new diperoxides from dibenzyl ketone, di-(4-methylbenzyl) ketone and 2,2-dimethylcyclohexanone whereas indan-2-one and 5,7-dihydro-6H-dibenzocyclohepten-6-one yield the corresponding triperoxides (1,2,4,5,7,8-hexoxonans) (7) and 1,5-diphenylpentan-3-one yields bis-(1-hydroperoxy-1-phenethyl-3-phenylpropyl) peroxide (5k).Ozonolysis of appropriate alkenes has been used to obtain new cyclic diperoxides formally related to 4′-methylacetophenone, propiophenone and deoxybenzoin.
