[EN] A series of geminal disulfone-containing compounds are described with utility in the treatment of HIV. An early stage inhibitor acts as a small molecule coreceptor-independent inhibitor of viral entry and can be used in combination therapy with other antiviral agents, including those described herein. [FR] Cette invention concerne une série de composés contenant des disulfones géminaux qui conviennent pour le traitement du VIH. Un inhibiteur de stade précoce agit comme co-récépteur de petites molécules/inhibiteur indépendant d'entrée virale et peut s'utiliser dans le cadre d'une thérapie combinatoire avec d'autres anti-viraux, dont ceux décrits ici.

An efficient procedure for palladium-catalyzedcoupling reactions of (hetero)aryl bromides and chlorides with primary aliphatic alcohols has been developed. Key to the success is the synthesis and exploitation of the novel bulky di-1-adamantyl-substituted bipyrazolylphosphine ligand L6. Reaction of aryl halides including activated, nonactivated, and (hetero)aryl bromides as well as arylchlorides with
