acid anhydride is postulated to be the active intermediate responsible for this successful amidation. This direct amidation is an atom- and step-economical reaction. A novel and facile boric acid catalyzed direct amidation between amino-azaarene compounds and carboxylicacids has been developed. The amidation proceeded cleanly and provided good to excellent yields of the desired amides. Boric acid

A series of 23 N-(Pyridin-3-yl)benzamides was synthesized and evaluated for their potential to inhibit human steroid-11 beta-hydroxylase (CYP11B1) and human aldosterone synthase (CYP11B2). The most potent and selective CYP11B2 inhibitors (IC50 values 53-166 nM) were further evaluated for their potential to inhibit human CYP17 and CYP19, and no inhibition was observed. Clear evidence was shown for N-(Pyridin-3-yl) benzamides to be a highly selective class of CYP11B2 inhibitors in vitro. (C) 2010 Elsevier Ltd. All rights reserved.
