[Figure not available: see fulltext.] A method has been developed for the preparation of new pyrazolo[3,4-b]pyridines and tetrahydropyrazolo[3,4-b]quinolinones by the reactions of 5-amino-1-aryl-1H-pyrazole-4-carbonitriles with aliphatic and cyclic 1,3-di

A facile synthesis of potential acetylcholinesterase (AChE) inhibitors, the tacrine analogues 3a-p, has been accomplished by direct cyclocondensation of 1-aryl-4- cyano-5-aminopyrazole with β-ketoesters using tin(IV) chloride as catalyst. The structures o
