- Nitrile Synthesis by Aerobic Oxidation of Primary Amines and in situ Generated Imines from Aldehydes and Ammonium Salt with Grubbs Catalyst
-
Herein, a Grubbs-catalyzed route for the synthesis of nitriles via the aerobic oxidation of primary amines is reported. This reaction accommodates a variety of substrates, including simple primary amines, sterically hindered β,β-disubstituted amines, allylamine, benzylamines, and α-amino esters. Reaction compatibility with various functionalities is also noted, particularly with alkenes, alkynes, halogens, esters, silyl ethers, and free hydroxyl groups. The nitriles were also synthesized via the oxidation of imines generated from aldehydes and NH4OAc in situ. (Figure presented.).

- Discovery of potent inhibitors of human and mouse fatty acid amide hydrolases
-
Fatty acid amide hydrolase (FAAH, EC 3.5.1.99) is the main enzyme catabolizing endocannabinoid fatty acid amides. FAAH inactivation promotes beneficial effects upon pain and anxiety without the side effects accompanying agonists of type-1 cannabinoid receptors. Aiming at discovering new selective FAAH inhibitors, we developed a series of compounds (5a-u) characterized by a functionalized heteroaromatic scaffold. Particularly, 5c and 5d were identified as extremely potent, noncompetitive, and reversible FAAH inhibitors endowed with a remarkable selectivity profile and lacking interaction with the hERG channels. In vivo antinociceptive activity was demonstrated for 5c, 5d, and 5n at a dose much lower than that able to induce either striatal and limbic stereotypies or anxiolytic activity, thus outlining their potential to turn into optimum preclinical candidates. Aiming at improving pharmacokinetic properties and metabolic stability of 5d, we developed a subset of nanomolar dialyzable FAAH inhibitors (5v-z), functionalized by specific polyethereal lateral chains and fluorinated aromatic rings.
