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
开发了两种立体选择性平行发散四步法,以获得N,N,N-三甲基(6-甲基-1,4-二恶烷-2-基)甲基碘化碘的所有四种对映体形式。对映体纯度是通过在手性位移试剂(+)-MTPA存在下的定量(1)H NMR光谱确定的。通过结合和功能测定法评估了所有毒蕈碱受体亚型所获得化合物的生物学特性。
