摘要:A method of preparing a 2,6 disubstituted anilines includes, reacting a 2-amino isophthalic acid diester with sufficient Grignard reagent R 2 CH 2 MgX to form the corresponding diol product, dehydrating the diol product to the corresponding dialkene; and hydrogenating the diol product to form the corresponding aniline. The 2,6 disubstituted anilines can be used to produce N-Heterocyclic Carbenes (NHCs). The NHCs can find application in various fields such as organic synthesis, catalysis and macromolecular chemistry. Palladium catalysts containing the NHCs are also described.

摘要:Novel N-hydroxyamide derivatives are disclosed. These N-hydroxyamide derivatives inhibit UPD-3-O—(R-3-hydroxymyristoyl)-N-acetylglucosamine deacetylase, an enzyme present in gram negative bacteria and are therefore useful as antimicrobials and antibiotics. Methods of synthesis and of use of the compounds are also disclosed.
