remained a focus of interest. In contrast to the conventional/traditional methods of etherification, herein, we have reported a more efficientmethod, which is better yielding and more general in application. The etherification of aryl halides by alkoxy/phenoxy silanes was catalyzed by copper acetate in the presence of cesium carbonate and oxygen in DMF at 145 °C. All the as-synthesized compounds were
A study of the development of reaction conditions for implementation of an activated Ullmann diaryl ethercondensation reaction that may be conducted without amino acid racemization and that has proven suitable for incorporation of a selectively-protected catechol is described and its application to the synthesis of l,l-isodityrosine (1) is detailed.

The viral serineprotease NS2B-NS3 is one of the promising targets for drug discovery against dengue virus and other flaviviruses. The molecular recognition preferences of the protease favor basic, positively charged moieties as substrates and inhibitors, which leads to pharmacokinetic liabilities and off-target interactions with host proteases such as thrombin. We here present the results of efforts
