- New Insights into the Reaction Capabilities of Ionic Organic Bases in Cu-Catalyzed Amination
-
The application of ionic organic bases in the copper-catalyzed amination reaction (Ullmann reaction) has been studied at room temperature, with sub-mol-% catalyst loadings, and with more challenging amines at elevated temperatures. The cation present in the base has been shown to have little effect on the reaction at standard catalyst and ancillary ligand loadings, whereas the choice of anion is crucial for good reactivity. A substrate scope carried out at room temperature with the best performing bases, TBAM and TBPM, showed both bases to be highly effective under these mild reaction conditions. Moreover, under sub-mol % catalyst loadings and room temperature conditions, TBPM gave good to excellent yields for a number of different amines and functionalized aryl iodides (14 examples). However, reactions involving more challenging amines gave little or no yield. By using more forceful conditions (120 °C) moderate to excellent yields of cross-coupled products containing more challenging amines was achievable using TBPM and to a lesser extent with TBAM. As part of this work a study on the stability of the organic bases at 120 °C was undertaken. TBAM is shown to decompose to give nBu3N and mono-butylmalonate at higher temperatures, and this can be correlated to a decrease in performance in the coupling reaction. The phosphonium cations in TBPM did not undergo analogous reactivity but were shown instead to experience some degree of deprotonation at the α-CH2 to generate phosphonium ylides. This however did not lead to a significantly degradation in the activity of the TBPM in the cross-coupling reaction.

- Novel phosphorescent tetradentate bis-cyclometalated ?C *N?N-coordinated platinum complexes: Structure, photophysics, and a synthetic adventure
-
A long but adventurous journal to the synthesis of tetradentate bis-cyclometalated ?C*N?N-coordinated platinum complexes is described, where ?C and N?N denote a five-membered chelation and C*N denotes a six-membered chelation. Initial ligand designs resulted in the selective cycloplatination to form a tridentate coordination complex. The structures of the tridentate coordination complexes were confirmed by the X-ray crystallographic studies. The selective formation of the tridentate coordination complexes was analyzed, which led us to an ultimate design of the ligand 15 and 16. Ligands 15 and 16 differ only in the N?N motif; a bipyridine-based N?N for 15 and a pyrazolylpyridine-based N?N for 16, respectively. In both cases, a forced consecutive double cycloplatination would be possible to form a ?C*N?N- coordinated platinum complex. As expected, the reaction of ligand 15 and 16 with K2PtCl4 in acetic acid at reflux produced 17 and 18, respectively. The coordination geometry was confirmed by the X-ray crystallography of the complex 17. The square planar geometry and dual intermolecular π-π and Pt-Pt interactions were revealed in the molecular packing. The photophysical properties of the complexes were studied. It was found that the complex 18 emitted intensely yellow phosphorescence at room temperature in deoxygenated solution, while complex 17 emitted red emission in a frozen glass matrix. Both compounds have the lifetime of the excited states in the scale of micro seconds. The DFT calculations were carried out to elucidate the frontier orbitals of the complexes, which are used in interpreting the electronic spectra of the complexes.

- Nickel-catalyzed synthesis of diarylamines via oxidatively induced C-N bond formation at room temperature
-
A nickel-catalyzed oxidative coupling of zinc amides with organomagnesium compounds selectively produces diarylamines under mild reaction conditions, with tolerance for chloride, bromide, hydroxyl, ester, and ketone groups. A diamine is bis-monoarylated. A bromoaniline undergoes N-arylation followed by Kumada-Tamao-Corriu coupling in one pot. The reaction may proceed via oxidatively induced reductive elimination of a nickel species.

- Kinesin spindle protein (KSP) inhibitors with 2,3-fused indole scaffolds
-
Mitotic kinesin spindle protein (KSP) is involved in the assembly of the bipolar spindle during cell division. On the basis of a common 2,3-fused indole substructure within the complex frameworks of terpendole E and other KSP inhibitors, the carbazoles with a bulky alkyl group were identified as a novel KSP inhibitory scaffold. Additionally, among several naturally occurring cell growth inhibitors with 2,3-fused indole structures,β-carboline alkaloids, harman and harmine, showed moderate inhibition of KSP.

- Synthesis and antitubercular activity of phenothiazines with reduced binding to dopamine and serotonin receptors
-
Analogs of the psychotropic phenothiazines were synthesized and examined as antitubercular agents against Mycobacterium tuberculosis H37Rv. The compounds were subsequently counter-screened for binding to the dopaminergic-receptor subtypes D1, D2, D3 and the serotonergic-receptor subtypes 5-HT1A, 5-HT2A, and 5-HT2C. The most active compounds showed MICs from 2 to 4 μg/mL and had overall reduced binding to the dopamine and serotonin receptors compared to chlorpromazine and trifluoperazine.
