Two stereoselective parallel divergent four-step procedures to obtain all four enantiomeric forms of N,N,N-trimethyl(6-methyl-1,4-dioxan-2-yl)methanaminium iodide were developed. Enantiomeric purity was determined by quantitative (1)H NMR spectroscopy in the presence of the chiral shift reagent (+)-MTPA. The biological profile of the obtained compounds was evaluated at all muscarinic receptor subtypes
