A practical electrochemical oxidation of unactivated C–H bonds is presented. This reaction utilizes a simple redox mediator, quinuclidine, with inexpensive carbon and nickel electrodes to selectivelyfunctionalize “deep-seated” methylene and methine moieties. The process exhibits a broad scope and good functional group compatibility. The scalability, as illustrated by a 50 g scale oxidation of sclareolide
Novel lincomycin derivatives are disclosed. These lincomycin derivatives exhibit antibacterial activity. As the compounds of the subject invention exhibit potent activities against bacteria, including gram positive organisms, they are useful antimicrobial agents. Methods of synthesis and of use of the compounds are also disclosed.
