Popis: A series of 2-sulfonamido-1,3,4,6,7,11b alpha-hexahydro-2H-benzo[a]quinolizines were synthesized and examined for alpha 2- and alpha 1-adrenoceptor antagonist activity on the rat vas deferens and anococcygeus muscle, respectively. A number of compounds in this series were shown to be potent and selective alpha 2-adrenoceptor antagonists. Studies on the resolved enantiomers of compounds 6, 10, and 16 showed that alpha 2-adrenoceptor antagonist activity resided primarily in the 2R,11bS isomers, related to the absolute configuration of the alpha 2-antagonist yohimbine, such that the benzene ring and sulfonamide groups in this series were superimposable on the pyrrole and ester groups of yohimbine.
