Cyclometallated Cp*Ir(N∧C)Cl complexes derived from N-aryl ketimines are highly active catalysts for the reduction of N-heterocycles under ambient conditions and 1 atm H2 pressure. The reaction tolerates a broad range of other potentially reducible functionalities and does not require the use of specialised equipment, additives or purified solvent.

3-c]pyridines, and relatedcompounds were evaluated for their ability to inhibit binding of [3H]-1-[1-(2-thienyl)piperidine and [3H]-N-allylnormetazocine to phencyclidine (PCP) and sigma receptors, respectively. A representative series of compounds was evaluated in behavioral assays to determine the ability of the compounds to induce PCP-like stereotyped behavior and ataxia. All of the compounds caused stereotyped
therapeutic approach for the treatment of neuropathicpain. Starting from lead compound (S)-1, we focused our optimization efforts on potency for N-type calcium channel inhibition and improvement of CYP inhibition profile. 2-[(1-Hydroxycyclohexyl)methyl]amino}-(1R)-(1-isopropyl-6-methoxy-3,4-dihydroisoquinolin-2(1H)-yl)ethanone oxalate ((R)-5r) was identified as a novel orallyactive small-molecule N-type

The previously unknown bistributyltin benzopinacolate was prepared by photolysis of benzophenone in the presence of bistributyltin and used for thermal formation of aryl radicals that undergo subsequent intramolecular addition to an imne bond in an ortho-substituent.
