3‐Methyl‐1,2,3,4‐tetrahydropyrimidine‐5‐carbaldehyde O‐substituted oximes 4 and 1‐(3‐methyl‐1,2,3,4‐tetrahydropyrimidin‐5‐yl)ethanone O‐substituted oximes 9 have been prepared as bioisosteric congeners of arecoline which is a muscarinic agonist for treatment of Alzheimer s disease. Starting from pyrimidine‐5‐carbaldehyde 1, formation of the 3‐methylpyrimidinium salt and subsequent reduction afforded
3-甲基-1,2,3,4-四氢嘧啶-5-甲醛O-取代肟4和1-(3-甲基-1,2,3,4-四氢嘧啶-5-基)乙酮O-取代肟9已被制备为槟榔碱的生物等排同源物,槟榔碱是一种用于治疗阿尔茨海默病的毒蕈碱激动剂。从嘧啶-5-甲醛1开始,形成3-甲基嘧啶盐并随后还原得到1,2,3,4-四氢嘧啶衍生物,为了纯度和稳定性,将其转化为草酸盐。使用 [3H]-N-甲基东莨菪碱 (NMS) 通过放射性配体结合测定法测定制备的化合物对克隆人毒蕈碱 M1 受体 (h-M1) 的结合亲和力。
