cis-2,3-Dihydro-4-perfluoroalkyl-1H-1,5-benzodiazepines were stereoselectively synthesized using a one-pot, catalyst-free, three-componentreaction. This novel, efficient and convenient approach was used to synthesize 22 related products in moderate to excellent yields, demonstrating the scope and potential economic impact of the reaction.

By low throughput examination of our chemical library, compound 7 was selected as a lead NK, antagonist with a K-i of 7.1 nM. Modifications of its structure led to the finding that the in vitro potency could be markedly enhanced by disubstituting the anilino phenyl ring as in compounds 13 or 22. Human binding data correlated rather well with results obtained with in vitro animal mice; compound 13 was the most active with ED50 of 0.001 and 0.3 mg/kg after iv and po administration respectively. Furthermore, antagonist 71 was found to be a potent inhibitor of SP-induced bronchoconstriction in guinea-pigs with an ED50 between 0.1 and 0.03 mg/kg iv. Furthermore, upon oral administration, 71 was observed to be active in a model of SP-induced bronchial hypersensitivity in mice, with an ID50 of around 3 mg/kg.
