2-Azabicyclo[2.2.2]octane derivatives have been used as conformational
ly constrained structure of BRL-32872, in order to investigate the eff
ect of molecular flexibility towards class III and class IV antiarrhyt
hmic properties. Extensive NMR studies allowed the determination of th
e configuration at C5. Stereoisomerism induces variability of biologic
al profile. (C) 1997 Elsevier Science Ltd.
