The synthesis of highly potent and selective acetylcholinesterase inhibitors, tacrine analogues with the structure of fused 4-aminoquinolines and 4-aminopyridines, has been accomplished by direct cyclocondensation of 1-aryl-4-cyano-5-aminopyrazoles with cyclic ketones using tin(IV) chloride as catalyst.
通过使用锡 (IV) 将 1-芳基-4-氰基-5-氨基吡唑与环酮直接环缩合反应,合成了高效选择性乙酰胆碱酯酶抑制剂,即具有稠合 4-氨基喹啉和 4-氨基吡啶结构的他克林类似物。 ) 氯化物作为催化剂。
