starting from methanols 1a-f via oxidation with pyridinium chlorochromate to aldehydes 2a-f, followed by a Grignard reaction of the latter. Reaction of 3a-f with ω-chloroalkyldialkylamine hydrochlorides afforded a series of aminoether derivatives 4g-t. Compounds 4i,m-p,s showed a good analgesic activity in the acetic acid writhing test in mice. Moreover, compounds 4h,1,s exhibited a moderate anti-inflammatory
从甲醇1a-f开始,通过用氯铬酸吡啶鎓氧化为醛2a-f,然后进行后者的格利雅反应,制备了一系列甲醇3a-f。3a-f与ω-氯烷基二烷基胺盐酸盐反应,得到一系列氨基醚衍生物4g-t。化合物4i,mp,s在小鼠的乙酸扭体试验中显示出良好的镇痛活性。此外,化合物4h,1,s在角叉菜胶诱导的大鼠水肿试验中显示出中等的抗炎活性。
