exists in equilibrium with its carbene form. Its reaction with thiophenes bearing at least one electron-accepting group was studied. Nucleophilic carbene insertion into Csp2−H bond of substituted thiophenes proceeded preferably at the 2(5) positions. Thiophenes featuring halogens at the 2 and 5 positions react much slower at the 3(4) position. A set of aldehyde was prepared. The reaction runs without

A novel class of alpha 7 nicotinic acetylcholine receptor (nAChR) agonists has been discovered through high-throughput screening. The cis gamma-lactam scaffold has been optimized to reveal highly potent and selective alpha 7 nAChR agonists with in vitro activity and selectivity and with good brain penetration in mice.
