Efficient and straightforward methods for the synthesis of 5-substituted 1 H -tetrazoles via multi-component reaction of α-dicarbonyl compounds, 2,3-diaminomaleonitrile and sodium azide without any catalyst has been reported. These general protocols provide a wide variety of N -rich heterocyclic...
Oligo-phenylene vinylene (oligo-PV) with two picolinamide side-groups and six methoxy end-groups was synthesized in order to be a fluorescent sensing molecule. Various metal ion solutions (1.5×10 −4 M) were added to the 1.5×10 −6 M acetonitrile solution of the fluorescent molecule. The...
A series of functionalized aza-polycyclic aromatic compounds were prepared by a superacid-promoted ring closing and opening reaction cascade. A reaction mechanism is proposed, which involves reactive dicationic intermediates. A key step in the conversions involves ipso protonation of an aryl...
1,3-Dipolar cycloaddition of nitrile imines with α,β-unsaturated five- and six-membered lactones, thiolactones and lactams gave ring-fused pyrazoles. Regioisomeric mixtures have been obtained with the 5-substituted pyrazole as the major cycloadduct. Only with the five-membered lactone the major...
The 1,4-dipoles generated from imines and DMAD have been shown to react efficiently with benzylaldehyde dipolarphiles in one-pot (4+2) annulation resulting in the diversity oriented synthesis of 1,3-oxazine derivatives in good to excellent yields.
A synthetic route to lactam analogues of the fungal STAT3 inhibitor galiellalactone is presented. The synthesis involves a one-pot tosylamide amide coupling/intramolecular Michael addition and an introduction of an α,β-unsaturation, regioselectively directed by the tosyl functionality. An...
A novel synthetic method for 2,5-disubstituted dihydropyrimidines was developed. The cyclization of 1,3-diaza-4-dimethylamino-1,3-butadienes having a N -protecting group ( N -Boc, N -Cbz, N - n -C 4 H 9 , N -Bn or N -Ph) with electron-deficient olefins, such as α,β-unsaturated carbonyl...
C 2 -symmetric metallocenyl planar phosphinooxazoline ligands ( 2 and 3 ) have been applied in the Ru(II)-catalyzed asymmetric hydrogenation of simple ketones. This type of ligands enjoys the advantages of dual reaction sites as well as larger steric hindrance than their corresponding C 1...
The conversion of α-ferrocenylalkyl- O -methyl ethers into the corresponding alcohols was successfully achieved by solvolysis in water/acetone mixtures. The content of water in the solvent markedly influenced the reaction rates. The reactivity of structurally different classes of ferrocenyl...
