Novel Benzothiazole, Benzimidazole and Benzoxazole Derivatives as Potential Antitumor Agents: Synthesis and Preliminary in Vitro Biological Evaluation

Molecules, 2012
In a previous hit-to-lead research program targeting anticancer agents, two promising lead compounds, 1a and 1b, were found. However, the poor solubility of 1a and 1b made difficult further in vivo studies.

A Joyful Journey: Tungsten(VI) and Tungsten(V) Fluorides Meet N‐Heterocyclic Carbenes and Cyclic (Alkyl)(Amino)Carbenes

Angewandte Chemie International Edition, EarlyView.
The first tungsten(VI) fluoride complexes coordinated with N‐heterocyclic carbenes and cyclic (alkyl)(amino) carbenes were synthesized and characterized. Reduction of these seven‐coordinated complexes afforded rare octahedral tungsten(V) fluoride complexes, a dinuclear fluoride‐bridged complex (cAACMe), or a seven‐coordinated (cAACMe) bis‐carbene ...
