Palladium-Catalyzed Three-Component Synthesis of Phenothiazines
Troels Dahl, Christian Wenzel Tornøe, Benny Bang-Andersen, Poul Nielsen and Morten Jørgensen, H. Lundbeck A/S

The formation of aromatic carbon-heteroatom bonds has traditionally been achieved by nucleophilic aromatic substitution or via the copper-mediated Ullman reaction. The palladium-catalyzed formation of aromatic C-N bonds extensively developed by Hartwig and Buchwald has provided a powerful alternative. While the aryl amination reaction is applicable even to aryl chlorides and activated phenols, the analogous C-O and C-S bond forming reactions have attracted less attention.

Phase Tranformation of Sodium Carbonate to Monohydrate
A. Shaikh, A.D. Salman, S. Mcnamara, G, Littlewood and M.J. Hounslow, Sheffield University

Sodium carbonate is the most widely used chemical compound in the world. The 50% of this used in glass industry is in the form of dense sodium carbonate. The process of transformation of sodium carbonate to sodium carbonate monohydrate is the key step in the production of dense sodium carbonate. In this present work systematic experiments were conducted by using online in-situ measurement techniques. It is shown that the kinetics of phase transformation process is highly temperature dependant.

From Medicinal Plants to Bioactive Drugs

The aim of our study was to analyze the antiproliferative activity effects on human tumor cell lines and the differentiating activity on human erythroleukemic K562 cells of different extracts derived from medicinal plants of Bangladesh and Lebanon.

Development of an Analytical Data Management System (ADMS) to Accelerate the Selection of a Suitable API Form Through Salt and Polymorph Screening
Raeann Wu, Peter Karpinski, Patrick Drumm, Karim Kassam, Michel R.J. Hachey and Michael Boruta, Advanced Chemistry Development Inc and Novartis Pharmceuticals Corp.

In this work, we discuss the acceleration of the preformulation process through the use of modern software systems. The data system discussed can read, process, store, retrieve, visualize and report a wide variety of data type—XRD, Raman, HPLC, NMR, TGA, DSC, chemical structures, properties and images—in a centralized and homogeneous way. A pilot study at a pharmaceutical company demonstrated possible time savings between 20% and 80% at various points in the preformulation workflow.
