Regioselective Synthesis of 3-Aminoimidazo[1,2- a ]pyrimidines with Triflic Anhydride

The regioselective synthesis of 3-aminoimidazo[1,2- a ]pyrimidines via triflic anhydride mediated amide activation and intramolecular cyclisation is reported. The nature of the added pyridine base allows access to both regioisomers from a simple common precursor. The method tolerates a range of functional groups and provides access to novel heterocyclic scaffolds.

Hydrazination of Pyridazines and Phthalazines

It is shown by 15N-labelling techniques that hydrazination of pyridazines partly occurs according to a reaction pathway, involving addition of the nucleophile (hydrazine), ring opening and ring closure (SN(ANRORC)-mechanism).It is also proved that phthalazines undergo hydrazination without ring opening (SN(AE)-mechanism).

Use of N-Protected Amino Acids in the Minisci Radical Alkylation

(Equation presented) The Minisci radical alkylation has been demonstrated on a range of commercially available glycine derivatives and proceeds in good to high yield. When extending the reaction to other amino acids, competitive oxidation of the initially formed radical was overcome by using the phthalimide protecting group.

Effect of lipophilicity modulation on inhibition of human rhinovirus capsid binders

To try and generate broad spectrum human rhinovirus VP1 inhibitors with more attractive physicochemical, DMPK and safety profiles, we explored the current SAR of known VP1 compounds. This lead to the identification of specific structural regions where reduction in polarity can be achieved, so guiding chemistry to analogues with significantly superior profiles to previously reported inhibitors.

New iridium complexes bearing C^N=N ligand for high efficiency OLEDs

Three iridium complexes, with 3-methyl-6-(2,4-difluoro-phenyl)pyridazine (mdfppya, C^N=N type ligand) as cyclometalated ligands, and picolinate (pic) or acetylacetonate (acac) as ancillary ligand, were synthesized and structurally characterized. Among these complexes,the homoleptic one, which contains two fluorine atoms on the cyclometalated phenyl moiety to lower the LUMO and a methyl group at the cyclometalated pyridazine part to raise the HOMO, possesses the shortest emission wavelength with peak of 506 nm. Importing ancillary ligands of picolinate (pic) and acetylacetonate (acac) yielded iridium complexes with emission of longer wavelength. The investigation of photophysical, electrochemical properties, as well as quantum chemistry calculation revealed optoelectrical property differences among them, corresponding principles were discussed. Photophysical, electrochemical features, quantum chemistry simulation and electroluminescence properties were systematically investigated. All complexes were applied to organic light-emitting diodes (OLEDs) as dopant emitters and the influence of ancillary ligands on device performance is significant. Based on pic-complex, maximum device efficiencies of 41.0 cd A?1, 33.9 lm W?1 and 11.62% were achieved. Additionally, this device exhibits extremely small efficiency roll-off. The reason for this good performance is mainly attributed to the high photoluminescence quantum yield and fast radiative decay rate of the phosphor, as wells rather matched energy levels in device.
