facilitated the Cu-catalyzed cross-coupling reactions of alkyl, aryl, or heterocyclic thiols with either alkyl, aryl, heterocyclic, or substitutedvinylhalides. This new catalytic system promoted the mild and efficient stereo- and regiospecific synthesis of biologically important vinylsulfides. The yields obtained using electron-rich substitutedvinylsulfides with this catalyst system are generally

Novel acrylic acid ethyl ester derivatives were synthesized and evaluated as potentialagents against Mycobacterium species. A versatile and efficient copper-catalyzed coupling process was developed and used to prepare a library of substituted acrylic acid ethyl ester analogs. Minimum inhibitory concentration assays indicated that two of these compounds 3 and 4 have greater in vitro activity against
