The commercially available and bench-stable Co(acac)2 ligated with bis[(2-diphenylphosphino)phenyl] ether (dpephos) was employed for selective room temperature hydroboration of nitro compounds with HBPin (TOF up to 4615 h−1), tolerating halide, hydroxy, amino, ether, ester, lactone, amide and heteroaromatic functionalities. These reactions offered a direct access to a variety of N-borylamines RN(H)BPin
amide, or sulfonamide were investigated to fit a hydrophobic substituent with up to two aryl groups within the tyrosine gate emerging from the mannose-binding pocket of FimH. The results were summarized into a set of structure-activity relationships to be used in FimH-targeted inhibitor design: alkene linkers gave an improved affinity and inhibitory potential, because of their relative flexibility combined

A process for the monoacylating of an aromatic primary diamine containing no anionic water-solubilizing group, preferably m-phenylene or p-phenylenediamine, which comprises reacting an acylating agent in aqueous medium with a mineral acid salt, preferably the hydrochloric acid salt, of the diamine wherein the reaction mixture is maintained at a pH of from 1.5 to 3.5 during the addition and reaction of the acylating agent.
