This paper describes the synthesis of 1,3,4,5-tetrahydropyrazolo[3,4,5-kl]acridine (2) and 11-amino-1,3,4,5-tetrahydro-azepino[3,2-b]quinolin-2-one (3) obtained by Schmidt reaction of 9-amino-3,4-dihydroacridin-1(2H)-one (1) and the preparation of 4,5-dihydro-3H-isoxazolo[3,4,5-kl]acridine (7) obtained in the same manner starting f rom 3, 4-dihydroacridine-1, 9 (2H, 10H) -dione (6) . The corresponding pyrazolo[3,4,5-de]quinoline (20) and isoxazolo[5,4,3-de]quinoline (18) are also reported. The compounds have been prepared with the aim of studying their possible activity as acetylcholinesterase inhibitors.
