Abstract

Proton magnetic resonance spectra of tropine and the two isomeric tropine N‐oxides have been analysed at 220 MHz. Chemical shifts in the N‐oxides are expressed relative to tropine (Δ__v__) and permit unequivocal structural assignments of the predominant isomer (1, equatorial N‐oxide) and the minor isomer (2).
