- Cyclization of Active Methylene Isocyanides with α-Oxodithioesters Induced by Base: An Expedient Synthesis of 4-Methylthio/Ethoxycarbonyl-5-acylthiazoles
-
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

- Kr?hnke pyridines: Rapid and facile access to Mcl-1 inhibitors
-
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

- Facile synthesis of cyclometalated ruthenium complexes with substituted phenylpyridines
-
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.
