In connection with the synthesis and epoxidation of campholenic and fencholenic derivatives some trimethylammonium iodides (2 and 4) similar to muscarin were prepared. They may be of interest for the investigation of the cholinergic receptor. The stereochemistry of the epoxytrimethylammonium iodide 4a was determined by NMR and X-ray analysis.
