the Pd-catalyzed amination of arenes to form N-aryl phthalimides with regioselectivity controlled predominantly by steric effects. Mono-, di-, and trisubstituted arenes lacking a directing group undergo amination reactions with moderate to high yields and high regioselectivities from sequential addition of PhI(OAc)2 as an oxidant in the presence of Pd(OAc)2 as catalyst. This sterically derived selectivity
The invention provides antimicrobial compounds and compositions, and methods of using them. The compounds and compositions include, for example, a compound of any one of Formulas I-X. The invention further provides methods of preparing the compounds, and useful intermediates for their preparation. The compounds can possess highly specific and selective activity, such as antibacterial activity and/or enzymatic inhibitory activity. Accordingly, the compounds and compositions can be used to treat bacterial infections, or to inhibit or kill bacteria, either in vitro or in vivo.
