Structurally robust tetradentate gold(III)-emitters have potent material applications but are rare and unprecedented for those displaying thermally activated delayed fluorescence (TADF). Herein, a novel synthetic route leading to the preparation of highly

Cyclization of tosylmethyl isocyanide with α-oxodithioesters in the presence of KOH is reported for the synthesis of 4-methylthio-5-acylthiazoles. Similarly, ethyl isocyanoacetate underwent cyclization with α-oxodithioesters to form 4-ethoxycarbonyl-5-acy

o-Phenylenediammines and o-Aminophenols were reacted with α-oxodithioesters in a highly regioselective fashion to give 2-methylthio-3-Aryl/heteroarylquinoxalines and 2-Acylbenzoxazoles in 55-94percent and 45-86percent, respectively, in the presence of p-T

The tumorigenic activity of upregulated Mcl-1 is manifested by binding the BH3 α-helical death domains of opposing Bcl-2 family members, neutralizing them and preventing apoptosis. Accordingly, the development of Mcl-1 inhibitors largely focuses on synthe

We have developed a new strategy that uses the Kroehnke synthesis for the preparation of various substituted phenylpyridines in excellent yields (up to 88%). Starting with the appropriate commercially available acetophenone, a variety of phenylpyridines substituted by either electron-donating (i.e. methyl, methoxy) or -withdrawing groups (i.e. bromide, nitro) on the phenyl ring are obtained in a two-step synthesis. The corresponding functionalized cyclometalated ruthenium complexes can be prepared with unusually high yields by using methanol as reaction solvent. The electrochemical data of the complexes demonstrate the strong σ-donating character of the anionic phenylpyridine ligand. X-ray analyses of four complexes show a shortening of the Ru-C bond associated with the elongation of only one of the five Ru-N bonds (trans effect). Wiley-VCH Verlag GmbH & Co, KGaA, 2006.
SYNTHESIS AND STRUCTURAL STUDY ON Α-SUBSTITUED-1-STYRYLPYRIDINIUM SALTS. REINVESTIGATION OF KROHNKE CONDENSATION

Kroehnke condensation of several cycloimmonium salts with p-dimethylaminobenzaldehyde has been studied.X-Ray diffraction, IR and Raman spectra, 1H- and 13C-NMR and UV spectra of the products are discussed, being compared, when necessary, with the starting pyridinium salts.All compounds showed the Z configuration, corresponding to the more stable structure, except one, in which steric factors were predominant.
