In order to prepare new tacrine-like compounds, the title compounds (VII), (X) and (XV) are synthesized. The synthetic pathway to (VII) represents a shorter and more suitable approach to prepare tacrine metabolites. An alternative route from (VIb) to compound (VIII), which exhibits very strong DNA b

✦ Synopsis
This paper describes the synthesis of 9-amino-2- and 4-hydroxy- and 2,4-dihydroxy-1,2,3,4-tetrahydroacridines 2 and of 9 -aminomethyl-1,2,3,4-tetrahydro- and 1,2,3,4,5,6,7,8-octahydroacridines 3 starting from the corresponding 9-carboxamido derivatives. A new synthetical pathway to 9-amino-2-hydroxyacridine 9 is also reported.
