The synthesis of some isochroman-4-spiro-4'-piperidines by intramolecular O-methylation of 4-aryl-4-hydroxymethylpiperidines with formaldehyde and their analgesic activity ("hot plate"test in mice) are reported. The introduction of the new ring led to compounds with weak analgesic activity.
报道了通过4-芳基-4-羟甲基哌啶与甲醛进行分子内O-甲基化反应合成一些异苯并二氢吡喃-4-螺-4'-哌啶及其镇痛活性(小鼠“热板”试验)。新环的引入导致化合物具有弱镇痛活性。
