title: Monoquaternary neuromuscular blocking agents based on 1-tetralone and 1-indanone.
abstract: The preparation of three isomeric 1-tetralone hydrozones 4 and three isomeric 1-indanone hydrozones 5 possessing a single quaternary ammonium center is described. Several of the compounds possessed significant neuromuscular blocking activity, and two approached suxamethonium in potency. 1H NMR evidence obtained from a study of the N,N-dimethylhydrozones indicated that the hydrazones adopted an E configuration in solution.
